Activity Overview
Students write exponential equations based on the percent of increase of college costs and will graph and interpret these equations. Students use an inflationary equation to project costs using another factor which affects future expenditures.
Before the Activity
See the attached Teacher Edition PDF file for notes and guidelines for this activity. The Technology Guide PDF file includes step-by-step calculator instructions with screen shots.
During the Activity
Students will:
Calculate the percent of change.
Write exponential equations in the form y = a(b)x, given a and b.
Use the exponential equations to do analysis and make predictions.
Graph exponential functions.
Directions:
Distribute the Student Edition PDF file to your class.
Follow the activity procedures outlined in the student document.
