Question

The graph h = −16t2 + 25t + 15 models the height and time of a ball that was thrown off a building where h is the height in feet and t is the time in seconds. At what height was the ball initially thrown off the building?

Answer 1

• 15 ft

Explanation:

Given

• The graph h = −16t² + 25t + 15

Initial point is the value of h at t= 0

• h = -16*0 + 25*0 + 15
• h = 15 ft

The ball was thrown at 15 ft height
