What are Functions?

Standard

Functions are an important concept and are therefore, heavily tested on the new SAT. It is important to become proficient with them. But, what is a function anyway? In mathematics, a function relates to an output that resulted from an input. It is like in computer science when you learn about input and output devices and the relationship between both. For example, you put in an input into the computer in the form of instructions, and it resulted in an output in the form of a printed document. In the real world context, other ways in which the concept of functions occurs it in factories where you have large machinery. The machines work in the same context of input and output.

A function is usually denoted by “f(x) =…” , the f, is not unique and any letter can be used.

A function has three main parts:

  1. The input
  2. The relationship
  3. The output

Example: “Multiply by 4” is a very simple function you can grasp.

Input = 5, Relationship = × 4, Output = 20.

Consider this: For an input at 40 what is the output?

Examples of functions

f(x) = x2 + 3

g(x) = 2x – 7

The above definition of a function is considered as the basic understandable definition. It goes deeper. A function may also be considered as a relation that uniquely maps one member of a domain unto another member of a range which is a subset of a codomain. This means, if you have a function which maps set A to B, it is an object f such that   is mapped onto one or more members of the range such that. The range is part of a codomain. This means that a function can be a many to one or one to one relation. If you have a one to many relation that is not a function. Let us look at range, domain and codomain to get a better understanding of the aforementioned definition. But first let us look at one to one and one to many mapping.

Understanding the difference between the range and the codomain is very critical. It even becomes more critical when doing further math such as pre-calculus where a function is undefined.

Example 1

What is the domain and range of the function: f(x) = 2x2 + 6?

To answer this question, you need to think about all the possible values than can be inputted into the function and get an output. By looking at the function you realize than any real number can be placed into the function to produce an output. Also, you may also realize that the set of integers can also be used. If you use any random integer for example -3, you can check

Thus f(-3) = 2(-3)2 + 6

= 2(9) + 6

= 18 + 6

= 22

You may also notice that all the output for the set of real numbers will be the same for the set of integers because of the x2. Therefore the domain is the set of integers. Since the set of real numbers is a subset of the set of integers, we can exclude it. Note that the domain does not have one set definition, because it could also be the set of counting number, whole numbers, etc. However for the range, you will never get a negative output, so the range could never be the set of integers, but it could possibly be the set of even numbers, however the range is the set {8, 14, 22…}. Though the question didn’t ask, but the codomain could be the set of counting numbers, since the output could be any possible counting number.

Evaluating Functions

Evaluating functions is quite simple, all you need to do, if plug in the value that is given, substitute the value for I, then solve the equation.

Example 2

Function f is defined by
f(x) = – 2x2 + 6x – 3, find f(- 2).

What you do in this instance, you substitute -2 for ‘x’ in the function then solve

= -2(-2)2 + 6(-2) – 3

= -2(4) – 12 – 3

= -4 – 12 – 3

= – 19

Example 3

Two functions f and g is defined by

f(x) = 2x + 7 and g(x) = -5x – 3, find (f + g)(x).

When you look at the question it might seem hard, but it is quite simple. You may note that (f + g)(x) denotes is the product of two numbers ideally. It can be expanded as such

(f + g)(x) = f(x) + g(x). As such, this is in a form that we can understand therefore it is:

f(x) + g(x) = (2x + 7) + (-5x – 3). Note: the brackets are there to show the two distinct functions

2x + 7 – 5x – 3 by grouping like terms”

2x – 5x + 7 – 3

= – 3x + 4

Therefore (f + g)(x) = – 3x + 4

Example 4

Two functions f and g is defined by

f(x) = 2x2 – 3x and g(x) = x + 1, find f (g)(-3).

What you see above is called a function of a function. It is quite easier than it looks. What is means that wherever you see x in function f, you are going to plug put the g function then plug in -3. Therefore:

f (g)(x) = 2(x + 1)2 – 3(x + 1). Thus, we first put the g function in the f function. Now we evaluate for:

f (g)(-3) = 2(-3 + 1)2 – 3(-3 + 1)

= 2(-2)2 – 3(-2)

= 2(4) + 6

= 8 + 6

= 14

Therefore f (g)(-3) = 14

If we were not asked to evaluate f (g)(-3), but just find f (g)(x)

The answer would just be: 2(x + 1)2 – 3(x + 1).

You may also note that a function can be graphed and in that context, the x is the domain and y is the range so sometimes you will see that f(x) = y.

Range, Domain and Codomain

The first diagram represents a one to one mapping, where each element of X maps exactly onto one Element of Y. The second diagram represents aone to many mapping where one element of X maps onto one of more element of Y.

A domain is simply all the possible values that can be inputted into a function to produce an output.

The range is simply all the output of a function.

The codomain is all the possible outcomes or output from a function.

Blended Learning

Standard

by Dr. Charice Hayes 


What is blended learning? 

Blended learning is traditional teaching combined with digital media or online learning. I like to also refer to this type of learning as “hybrid” learning. 

Why use blended learning?

  • Research suggests that blended learning is more effective than learning in a traditional setting. 
  • Blended learning improves digital literacy, along with online learning skills. 
  • Some teachers/professors are using flip learning
  • Blended learning aligns with college and workplace readiness. 

How can you transform a traditional classroom into a blended classroom? 

  • You can use online videos to supplement instruction. 
  • You can use the flipped learning model.
  • You can incorporate chats and discussion boards. 
  • You can use software such as Socrative.com.

What are your thoughts on blended learning? Please share your thoughts. 

2016 Year in Review 

Standard

Contributed by Dr. Charice Hayes CEO


It has been a continued promising year for All 4 One Tutoring. This past year, we’ve put some things in place to diversify and expand our company and programming. Within the first five months of 2016, we were able to hire tutors and instructors in our after-school program. In November, we’ve started the process of hiring a marketing intern. This additional hiring helped us grow and continue to mirror the company’s mission statement. We’re looking forward to hiring more staff members in the first 3-4 months of 2017. 
In the summer of 2016, we continued a summer tutoring program. Some of our clients wanted to avoid that dreadful “summer learning loss.” We conducted online and face-to-face sessions. We plan to do the same summer 2017. 

During the summer of 2016, All 4 One Tutoring had to close one of its offices due to space. We are currently looking for a larger office (That’s a good thing!) We still have office space at The Empowerment Academy

Our after-school program continues to get praise by administrators, community leaders, and parents. This school year, we continued with more project-driven instruction and projects. We have even purchased state of the art headphones for our learning labs.

We are looking forward to finishing the 2016-2017 school year with continued success. 

Last but not least, for a fourth year in a row, All 4 One Tutoring‘s income and net profit has increased. Our income has increased 40% from 2015, and our net profit has increased 30%. We would love to see this trend occurring year after year. Being the owner of such a blossoming and empowering organization is such an honor. We are proof that when we work together to achieve a shared goal, we can expand quality education and training so that everyone can strive for positive social change. We have more plans underway for 2017!!!!
  

Here’s a look at All 4 One Tutoring’s agenda in 2017:
-more partnerships (international and nationwide)

-opening a bigger office

-increasing staff 

-offering more training and workshops 

-revisiting 21st CCLC (Century Community Learning Centers)

-expanding our foreign language service

-developing an internship program 

I’d like to thank everyone who has had a positive impact and who has supported All 4 One Tutoring this year previously, and I always look forward to your continued support. Together we can reach the goal of educational EMPOWERMENT and provide positive SOCIAL CHANGE.
