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 55°, its height, f(x), in feet, can be modeled by
f(x) = - 0.02x2 + 1.4x+ 5.3, 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.
