A frog is sitting on a stump 6 feet above the ground. It hops off the stump and lands on the ground 4 feet away. During its leap, its height h is given by the equation h equals negative 0.5 x squared plus 0.5 x plus 6
h=−0.5x2+0.5x+6 where x is the distance in feet from the base of the stump, and h is height in feet. How far was the frog from the base of the stump when it was 3.71 feet above the ground?
