WEST Middle Grades Math: Properties of Functions - Videos & Lessons

About This Chapter

Washington state now uses the National Evaluation Series (NES) examination rather than the WEST Middle Grades Math examination. Use the video lessons in this chapter to review the properties of functions and to answer related questions on this test.

WEST Middle Grades Math: Properties of Functions - Chapter Summary

Watch this chapter's online video lessons in order to strengthen your knowledge of function operations. Learn about the different kinds of transformations you can do with functions. You may also explore the process of composing functions as you prepare to take the WEST Middle Grades Math examination. This chapter can help you to:

Explain the basics of functions
Transform and graph functions
Perform function operations
Calculate domain and range for a function
Review function notation
Confirm and write inverse functions
Tell the difference between linear and nonlinear functions

The short video lessons in this chapter can be used as valuable study tools that help you prepare for the WEST Middle Grades Math examination. The informative lessons are presented by credentialed instructors who will answer your questions about functions. Feel free to watch the lessons at your own pace and to refer to the text transcripts at any time. Self-assessment quizzes and a practice chapter examination are included to test your knowledge.

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.

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!

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!

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.

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.

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.

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!

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.
