Activity Overview
Students will analyze a plan that an online music provider offers. Using this plan, the students will investigate how the prices of the plan affect the multiple representations of a function and how price changes are reflected in the multiple representations. This is a student centered activity. It is important that questioning techniques be used to guide students to make their own conjectures about rate of change and the y-intercept and their effects in applied situations.
