A rock is thrown from one side of a river to another. The function h(t) = −16t2 + 80t + 30 gives the height in inches of the rock t seconds after it has been thrown.

Question

Does it make sense to find h(−10) in the context of this problem?

Answer 1

No, it does not make sense to find h(-10) in the context of this problem because time cannot be negative and it does not make sense for the rock to be thrown 10 seconds before it actually was thrown.
