When a certain ball is dropped the function f(x)=4.5(0.65)^x modes its height in feet after each bounce where x is the bounce number. To the nearest hundredth, what is the height after the third bounce?

A. 0.98

B. 1.24

C. 1.90

D. 0.80

B

Step-by-step explanation:

In this question, we are told to calculate the height after the third bounce. From the question, we are made to know that x represents the bounce number.

Thus, mathematically we just plug the value 3 into the exponential equation.

f(x) = 4.5(0.65)^x

f(3) = 4.50(0.65)^3 = 1.2358125 which is approximately 1.24
