## Unit 3: Complex Numbers and Exponential Functions

### Overview

*This unit looks at complex numbers and explores their purposes in solving real world applications. Additionally, it focuses on exponential functions as a percent rate of growth or decay. Logarithmic functions are briefly explored as the inverse of exponential functions, and students learn to use exponential and logarithmic functions to model real world data.*
