In this activity, students will model the relationship between the year and average income, average price of a house, and average price of a car using exponential functions. Then students will answer questions related to the models to gain a deeper understanding of exponential functions.
Before the Activity
Transfer the RememberWhen.tns file onto all the student handhelds. The document contains directions for students to work individually but depending on their current familiarity with regression equations and exponential functions, groups of 2-3 students would be best.
