Alisha hits the golf ball for a long drive on the fairway. If the dimples on the ball did not give it loft, the path of the ball could be described using the equation y=-0.0036 (x+1)(x-186) . The distance from the point of impact is the x-value, and y is the height. Both are measured in metres. How much higher was the ball just before it was struck tha when it landed down the course?
