Solve the following equations and write your answer in simplest form.

A rock falls from a cliff 144 feet high. The function

models the height of the rock as it falls, where h is the height in feet and t is the time in seconds. 

Answer question 9,10, and 11 using the information above.

3

After how long will the rock land on the ground?

4

Are all solutions of h(t) = 0 viable? Explain your reasoning. Then state a reasonable domain for h(t).

4

The function

allows you to step back in time after the rock lands on the ground. Explain how to obtain its graph from the graph of h. State the domain of g, then pick an endpoint of the domain and explain why g makes sense for that value.
