An athlete whose event is the shot put releases a shot. When the shot, whose path is shown by the graph to the right, is released at an angle of 35°, its height, f(x), in feet, can be modeled by f(x) = -0.01x^2 + 0.7x + 5.8, where x is the shot's horizontal distance, in feet, from its point of release. Use this model to solve parts (a) through (c) and verify your answers using the graph.
