(a) Find the height of the ball (in feet) above the ground 2 s after its released.
That's just h(2)
h(2) = -16(2²) + 80(2) + 4 = -64 + 160 + 4 = 100
Answer: 100 feet
(b) Find the height of the ball (in feet) above the ground 4 s after its released.
That's just h(4)
h(4) = -16(4²) + 80(4) + 4 = -256 + 320 + 4 = 68
Answer: 68 feet
