Math Problem Statement
PROBLEM
Mark and James love to play volleyball. Suppose Mark tossed a volleyball to James who is 12 ft away. Midway between them is a volleyball net, the top of which is 7 ft high. The ceiling of the gymnasium is 25 ft high. When Mark tossed the ball to James, the shape of its path forms a parabola. The volleyball is 4 ft off the floor when it leaves Mark's hand, and James catches the volleyball 4 ft off the floor as well.
Write the equation that models the path of the volleyball if it passes midway between the net and the celling. Assume the origin is on the point midway through the volleyball court.
