Jill’s coach used a computer program to help her improve the distance she can throw a softball. The computer gave a readout of t
he path of her best throw. The path of this throw was represented by the quadratic equation
y = –0.15x2 + 1.3x + 4, where x represents the number of feet the ball traveled and y represents the height of the ball in feet. Use the graphing calculator to graph the equation. At what distance did the ball hit the ground? Round your answer to the nearest hundredth.
