Question

The function h(t) = -16t^2 + 144 represents the height, h(t), in feet, of

an object from the ground at t seconds after it is dropped. A realistic
domain for this function is

Answer 1

- 16t^2 +144 you can rewriting in this form 144 -16t^2 = (12 -4t)(12+4t)

12-4t=0

12 =4t divide both sides by 4

t=3
