A ball is thrown upward and outward from a height of 8 feet. The height of the ball, f(x), in feet, can be modeled by f(x)=-0.4x^2+2.1x+5 where x is the ball's horizontal distance, in feet, from where it was thrown Use this model to solve parts (a) through (c). a. What is the maximum height of the ball and how far from where it was thrown does this occur? feet from the point of release. feet, which occurs The maximum height is (Round to the nearest tenth as needed)
