I JUST NEED PART B EVERYTHING ELSE IS ANSWERED

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 +5.4 ,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.

I JUST NEED PART B EVERYTHING ELSE IS ANSWERED

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 +5.4 ,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.
