8. The Art of Modeling

10. Graphing Calculator - Exponential Regression Press STAT then EDIT 1. Type in the values in List 1 (x values) and List 2 (y values). Then STAT, move over to CALC and press 0. You will get values for a, b, r and r 2 . The values of a and b go into the equation y= a*b^x or y=ab x .
