A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height, h (in feet), from the ground is modeled by h-16t2+56t where t is measured in seconds. What is the practical domain in this situation?

h = -16t² + 56t

0 = -16t² + 56t

0 = -16t(t - 4)

0 = -16t 0 = t - 4

0 = t 4 = t

Domain: 0 ≤ t ≤ 4 Interval Notation: [0, 4]

NOTE: 0 seconds is the moment the ball is being kicked. 4 seconds is the moment it lands on the ground.
