d) What is the equation of the axis of symmetry for this graph?

Answer:

3) The path of a falling object is given by the function 0 0

2 s ? ?16t ? v t ? s where

0 v represents the initial velocity in ft/sec and 0 s represents the initial height in feet.

a) If a rock is thrown upward with an initial velocity of 64 feet per second from the top of

a 25-foot building, write the height (s) equation using this information.
