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 =?
