1. The problem statement, all variables and given/known data A basketball is thrown into the air, and it's height is determined by h = 3/4t(20-t) where t = time. 2. Relevant equations What is the greatest height the ball reaches 3. The attempt at a solution Ok so i tried to graph this out but stuffed up, a bit hard to show here. So first i expanded the rule into h=15t-3/4t^2 or h=-3/4t^2+15t Now i'm just wondering how i would graph that?
