In the context of the problem, the value of \( 7 \) represents the initial height of the rock when Kenny is holding it. Specifically, it indicates that the rock is 7 feet off the ground at the moment it is thrown. This height serves as the starting point for the rock's motion before it begins to fall due to gravity.
Kenny is standing on top of a boulder at his neighborhood pond. He picks up a small rock, so that it is 7 feet off the ground, and throws the rock into the pond. The height of the rock after t seconds can be modeled by the expression -16^2 + 32t + 7. What does 7 represent in the context of the problem.
