A player throws a football across the field. The equation h(t) = -16t^2 + 44t + 3.5 models the height, h (t) in feet of the football as a function of time, t in seconds.  a. Is this function linear, exponential, or a quadratic? How do you know?

b. What was the initial height of the football? What can you feature would represent there’s only graph of the function?

c. What is the maximum height of the football? What key feature would represent this on a graph of the function??
