Example 1: Nonlinear Functions in the Real World

This Instructional Activity is a part of the Lesson 5, Unit 6, Grade 8. Read through the scenarios as a class. A linear function is used to model the first scenario, and a nonlinear function is used to model the second scenario. Not all real-world situations can be modeled by a linear function. There are times when a nonlinear function is needed to describe the relationship between two types of quantities.
