The Price is Wrong: How to Not Get Ripped Off (Algebra 1)

Introduction

How do you know if you are getting a good deal, or getting ripped off?

Essential Questions

• What is exponential behavior and what data sets can be modeled using exponential functions?

• What do exponential functions and their graphs tell us about expected outcomes?

• How is exponential growth and decay modeled?

• How can models, graphs, and functions help predict outcomes for exponential functions?

• Why are functions and graphs useful for representing exponential data?
