# Ch 10: Functions in Math

Review math functions by watching brief video lessons. You can learn all about the necessary conditions to make true math functions and then learn how to write those functions using the video lessons and quizzes.

## Functions in Math - Chapter Summary

Mathematical functions are just rules or special equations that turn one number into another. This chapter explains function notation and how vertical line testing can find out whether an equation is really a function. You can learn to compose, add, subtract, multiply, divide, evaluate, manipulate and graph functions through the lessons in this chapter.

Practice problems are included to give you plenty of experience. In addition, you can also explore polynomial, piecewise, periodic, recursive and parametric functions. Can't wait to get started? Here's a list of concepts you'll find in this chapter:

• Transformation types
• Methods for performing function translations
• Domain and range of a function
• Inverse functions and the horizontal line test
• Compounding and manipulating functions
• Factoring and simplifying polynomials
• Finding the domain, graphing and translating piecewise functions

Each lesson offers a video presentation, transcript and quiz. The helpful video tags can show you exactly where on the videos certain concepts appear. The short quizzes are multiple-choice and are useful for helping you gauge your comprehension of the material.
