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 65°, its height, f(x), in feet, can be modeled by f(x) = - 0.04x? + 2.1x + 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. 20 40 60 80 100 Shot Put's Horizontal Distance a.
