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 30°, its height, f(x), in feet, can be modeled by f(x) = -0.01x2 +0.6x + 5.9, 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.
