4. A football is thrown in the air from an initial height of 4 feet with an upward velocity of
46ft/sec. The function
h (t) = -16t^2 +46 t + 4 gives the height after t seconds.

b. Find the maximum height?
c. How long does it stay in the air before it hits the ground?
d. Draw a picture and label the starting point, the vertex and the time that it hits the ground.
