# Ch 7: Functions and Graphs

Use these video lessons and quizzes to help you understand the differences between odd, even, one-to-one and inverse functions. Learn how to determine their domain and range, perform function transformations and solve function operations.

## Functions and Graphs - Chapter Summary

If you need a refresher on mathematical functions and graphs, this chapter's got you covered. Lessons begin with tips for identifying functions and writing them with the correct notation. You can learn how to use the vertical line test to determine whether or not a graph of an equation is a function and review rules for finding the domain and range. Instructors also cover steps for identifying even, odd and one-to-one functions and writing and graphing an inverse function.

Methods for performing the rotation, dilation, translation and reflection transformations used to shift graphs on a plane are discussed in the second half of the chapter, as are tips for adding and subtracting functions. You can also learn how to perform the correct order of operations or use the quotient of powers to multiply and divide them. The chapter concludes with instruction on composing functions and using graphs to conjecture identities. Video lessons are designed to cover the following main topics:

• Types of functions
• Function domain and range
• Transformation of functions
• Function operations

These lessons include examples and practice problems to help you master the steps required to solve functional equations. Content is available in the form of short, engaging videos and transcripts that include links to supplemental text lessons, which you can use to review some of the mathematical terminology you're not quite familiar with. There are also self-assessment quizzes that allow you to practice solving problems.
