Ch 19: MEGA Middle School Math: Properties of Functions

About This Chapter

Further your understanding of various mathematical functions in preparation for the Missouri Educator Gateway Assessments (MEGA) Middle School math exam. These video lessons and quizzes can help you correctly answer these types of questions on the test.

MEGA Middle School Math: Properties of Functions - Chapter Summary

Use this chapter's lessons to help you review function notation, composition and operations. Your mastery of this material will ensure that you can teach these subjects to 6th - 8th grade students. Once you have viewed these lessons, you should be comfortable with:

  • Explaining the basics of a function
  • Transforming one type of function into another
  • Detailing the types of transformations
  • Applying arithmetic operations to functions
  • Finding inputs and outputs of a function
  • Describing an inverse function
  • Evaluating linear and non-linear functions

In the video lessons, you can jump from one subject to another, while the accompanying transcript places key terms in bold. This makes review of the material simple and engaging. Quizzes allow you to assess what you've learned by using a multiple-choice format as found on the actual MEGA exam.

MEGA Middle School Math: Properties of Functions - Chapter Objectives

What is a Function: Basics and Key Terms

1. What is a Function: Basics and Key Terms

Mapping numbers sounds complex, but we do it when we buy gasoline. We pump gasoline, and the gas station charges us based on the amount of gas that we pump. Learn how this relates to functions while reviewing the basics and notations in this lesson.

Transformations: How to Shift Graphs on a Plane

2. Transformations: How to Shift Graphs on a Plane

What is a transformation? Well, it's something that transforms one function into another! To see what I mean and how that looks, check out this lesson!

How to Add, Subtract, Multiply and Divide Functions

3. How to Add, Subtract, Multiply and Divide Functions

Adding, subtracting, multiplying and dividing functions is about as simple as substituting in expressions and then just doing whichever operation it asks you to do. Check out this video lesson to see some examples of this and learn just how easy it is!

What Is Domain and Range in a Function?

4. What Is Domain and Range in a Function?

The domain and range are the possible outputs and inputs of a function. In this lesson, learn about what might restrict the domain and how to figure out the domain and range from a graph.

How to Compose Functions

5. How to Compose Functions

Function composition is the process of putting two or more functions together. This video lesson will explain how this process works and also show you how to evaluate functions that have been composed.

Inverse Functions

6. Inverse Functions

Inverse functions are two functions that do exactly opposite things. Check out this lesson to learn about how to write inverse functions, find inverse functions, and predict whether or not they exist.

Applying Function Operations Practice Problems

7. Applying Function Operations Practice Problems

In this lesson, learn how to apply all the different properties of functions to solve complex problems. From function operations and composition to domain and range, get your practice here!

Linear and Nonlinear Functions

8. Linear and Nonlinear Functions

After watching this video lesson, you'll be able to tell the differences between linear and nonlinear functions. You'll also be able to identify both types just by looking at graphs.
