Kennith is jumping off the diving board at the city pool. His height is modeled by the quadratic function h(t) = -16t2 + 16+ + 20, where h(t) = represents height above water (in
feet), and t represents time after jumping in seconds.
What is Tom's height above water at 1 second.

What expression is equivalent to 1/2(2+3x-6)
