## Units

### Unit 1: Exponential Functions

In this lesson, we introduce the exponential function and use it to describe a variety of applications involving exponential growth and exponential decay.

In this lesson, we discuss the domain, range, intercepts, and asymptotes of a basic exponential function.

In this lesson, we determine the equation of an exponential function describing a given table of values or graph. We also show how to use finite differences to identify data sets that are representative of exponential processes.

In this lesson, we find an equation to describe an exponential function that has undergone reflection, stretch, and translation transformations. We also look at how to graph transformed exponential curves.

In this lesson, we see that a given exponential function can be written in different bases.

In this lesson, we look at how to develop mathematical models to describe exponential processes using transformed exponential functions.

This is a collection of additional, and sometimes challenging, problems that extend the material covered in this unit, connect material from different lessons, and further explore real-world applications.
