# Chapter 8: Exponential and Logarithmic Functions

Difficulty Level:

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

## Introduction

In this chapter, we will analyze two new types of functions, exponents and logarithms. Up until now, the variable has been the base, with numbers in the exponent; linear, quadratic, cubic, etc. Exponential functions have the variable in the exponent. Logarithmic functions are the inverse of exponential functions. We will graph these functions, solve equations, and use them for modeling real-life situations.
