Graph the function using its intercepts.
What are the coordinates of the x-intercepts?
What is the axis of symmetry (in the form of x=h)
What is the vertex?
Describe the transformation of:
Stretch or Compression?(If a=1 or a=-1, then write none)
Opens upward or downward?
Horizontal shift? (If there is no shift write none)
Vertical shift? (If there is no shift write none)
Axis of Symmetry? (x=h)
Vertex (h,k)
What is the graph of the function?

A diver jumps from a dividing board 32 feet above the water with an initial velocity of 12 feet per second. The height h, in feet, of a the diver t seconds after she jumped can modeled by the function h(t) = -16t² + 12t + 32.
For all your answers round to two decimal places.
Find the height of the diver 1 second after he jumped off the board.
How long did it take for the diver to reach a maximum height above the water?
What is the diver's maximum height?
After how many seconds did the diver enter the water?
