The function h of t is equal to negative 16 t squared plus 28 t plus 500 represents the height of a rock t seconds after it is propelled by a slingshot. What does h of 3 point 2 represent?

In the function h(t), t represents the time in seconds, and h(t) gives the rock’s height at that time. Therefore, h(3.2) represents the rock’s height 3.2 seconds after it is propelled. The correct choice is “the height of the rock 3.2 seconds after it is propelled.”
