The vertex of the parabola represents the maximum height of the ball as it travels toward the basket. The vertex is given in the problem as 14 feet horizontally from the player and 10 feet up.
BTW, a standard basketball hoop is 10 feet off the ground, so this shot has zero chance of going into the basket. ;-)
