Motion. An object is thrown up from the top of a building that is 320 feet high. The equation y = – 16t2 + 128t + 320 gives the object's height (in feet) above the ground at any time t (in seconds) after the object is thrown.

a. What is the height of the object after 0, 1, 2, 3, 4, 5, and 6 seconds?


b. Sketch the graph of the equation y = – 16t2 + 128t + 320.


c. What part of the graph represents the physical aspects of the problem?


d. What are the intercepts of this graph, and what do they mean?
