the graph is a parabola, with vertex at t=1
h(1) = 20

Hello,
I did this question for homework, but my teacher said it was wrong and she didn't explain how it was supposed to be done. So could you please tell me how I am supposed to do this step by step?
"A baseball is thrown from the top of a building and falls to the ground below. The height of the baseball above the ground is approximated by the relation h = -5t2 + 10t + 15, where h is the height above the ground in metres and "t" is the elapsed time in seconds. Determine the maximum height that is reached by the ball.
Thank you very much!
