Overview

The purpose of this unit is to examine the inverse relationship between exponential and logarithmic functions. You will also explore how exponential and logarithmic functions are used to solve a wide variety of problems.

Common applications of exponential functions are compound interest and depreciating value. Logarithmic functions are used for half-life problems, logarithmic scales such as the Richter scale, and pH problems in chemistry.

In this unit, you will learn to identify and use exponential growth and decay functions. You will learn the definition of a logarithm and its connection to exponential functions, and use this inverse relationship to manipulate exponential and logarithmic functions to solve real world problems. You will also learn to graph exponential and logarithmic functions.
