A frog sitting on a stump 4 feet high hops off and lands on the ground. During her leap, the frog's height h in feet is given by the equation h = - 0.5d ^ 2 + d + 4 , where dis the horizontal distance in feet from the base of the stump . A : What was the frog^ prime maximum height B : How far from the stump did the frog land C: What was the frog's horizontal distance from the log at her maximum height?
