Jeffe and Tomas collected the following data for a bouncing basketball. What is their rebound ratio as a percent? Write a model for their data and then sketch a graph of the situation. Homework Help ✎
Bounce number (x)
Height, cm (y)
Look at the ratios of the successive y-values.
Use the general form of an exponential equation: y = a•bx. The parameter, b, is the constant ratio, 0.8.
To find the a-value, find the 0th term.
To find the 0th term, divide the first term, 80, by 0.8
