Comparing Linear and Exponential Data

#### Activity Overview

Compare a linear and an exponential relationship.

#### Objectives

• Students will use a table and a graph to compare the changes in linear and exponential expressions as x is increases.
• Students will recognize that as x increases, a linear expression increases at a constant rate (additively) while an exponential function increases multiplicatively.

#### Vocabulary

• exponential function

#### About the Lesson

This lesson involves moving a point that changes the value of x and observing and comparing the values of a linear expression and an exponential expression. As a result, students will:

• compare linear and exponential expressions, and compare linear and exponential functions.
