# Chapter 7: Roots, Radicals, and Function Operations

Difficulty Level:

**At Grade**Created by: CK-12

## Introduction

This chapter extends what we have learned about polynomials and exponents and applies those ideas to square root and cubed root functions. First, we will introduce rational exponents and simplify these expressions. We will also solve equations with radicals and rational exponents. Then, we switch gears a little and learn how to find the inverse of a function as well as how to add, subtract, multiply, divide, and compose them.
