Add an EXPONENTIAL trend line and equation to the graph. Write the exponential equation below:
__________ Based on the exponential equation in a, what will be the height of bounce number six?
__________ On what bounce number will the bounce height be 17?
__________ According to the International Tennis Federation a tennis ball used in tournament play must meet certain rebound (bounce) specifications. A ball dropped from a 100 inches must rebound between 53 and 58 inches. After bounce five the tennis ball fell from 100 inches. Does the bounce height calculated in b meet specification?

In the Tennis Industry Magazine article Racquet Handle Weighting and Maneuverability Rod Cross notes that, "Inspection of 320 different racquets ... shows that almost every light racquet is head heavy and every heavy racquet is head light." The article goes on to discuss the reasons tennis racquets are designed this way. The following table derives from the article.
