![6. The height of an object that is traveling through the air can be well modeled by a quadratic function that
opens downward. An object is fired upward and its height in feet above the ground is given by:
h(t) =-16r +64t +80
where the input, t, is the time, in seconds, the object has been in the air
(a) Using your calculator, sketch a graph of the object's
height for all times where it is at or above the
ground.
