9. The graph represents the path of a football kicked by a player, where x is the horizontal
distance (in yards) and y is the height (in yards). The player kicks the ball a second time
so that it travels the same horizontal distance, but reaches a maximum height that is 6
yards greater than the maximum height of the first kick. Write a function that models
the path of the second kick.
y=-0.02(x - 30)2 + 18
