A ball is thrown upward and outward from a height of 7 feet. The height of the ball, $$f(x)$$, in feet, can be modeled by $$f(x)=?0.4x^2+2.7x+7$$ a. What is the maximum height of the ball and how far from where it was thrown does this occur? The maximum height is feet, which occurs feet from the point of release. (Round to the nearest tenth as needed.) b. How far does the ball travel horizontally before hitting the ground?
