Problema Solution

The equation y=−3.5x^2−0.5x+65 models the height of a ball in inches for each bounce.

What is the best approximate for the height of the ball after the 3rd bounce?

Answer provided by our tutors

Plug x = t into y=−3.5x^2−0.5x+65

y=−3.5*3^2−0.5*3+65

y=32 in

The height of the ball after 3rd bounce is 32 inches.
