Question 15
When a tennis ball is dropped, it rebounds to 75% of its initial height. A tennis ball is dropped from an initial height of 8 feet. Which function defines the ball’s maximum height after each bounce, n?

A
f(n)=8(0.75)n

B
f(n)=8−2n

C
f(n)=8(0.75)n−1

D
f(n)=8−0.75n

Answer:

  A  f(n)=8(0.75)^n

Step-by-step explanation:

After the first bounce, the height is 8·0.75 = 6 ft. Each subsequent bounce multiplies the previous height by 0.75, so the height after n bounces is ...

  f(n) = 8·0.75^n . . . . matches choice A
