A baseball player hits a ball towards a 20-foot wall 400 feet away. The path of the ball is modeled by the function, f(x)=-0.002(x-220)^2 +86, where x is the distance of the ball from the batter and f(x) is the height of the ball. Based upon the function, f(x), what is the maximum height of the ball will reach?

At how many feet from the batter will the ball be at its maximum height?

Will the ball clear the wall?
