The function h (t) = - 16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot.

What does h (3.2) represent?

You would substitute t in the equation for 3.2 ... - 16 (3.2) squared+28 (3.2) + 500 then solve. To solve you multiply first so - 16 (3.2) squared and 28 (3.2), you should get - 51.2squared and 89.6. When squaring - 51.2 you should come up with 2,621.44 then you put it into the equation and add. 2,621.44 + 89.6 + 500 = ?
