Mathematical Modeling: A video of the path of a ball thrown by a baseball player was analyzed with a grid covering the TV screen. The video was paused three times, and the position of the ball was measured each time. The coordinates obtained are shown in the table. (
(a) Use a system of equations to find the equation of the parabola
(b) Use a graphing utility to graph the parabola.
(c) Graphically approximate the maximum height of the ball and the point at which the ball struck the ground.
(d) Analytically find the maximum height of the ball and the point at which the ball struck the ground.
(e) Compare your results from parts (c) and (d).
