Parts of a Quadratic

A sailfish jumps out of the water, and its path is represented by the equation h=-16t²+48t, where h is height and t is time.  What would the vertex tell me about the problem?

• the time when the fish is at its highest point above the water.
• the time when the fish hits the water
• the height that the fish jumped out of the water
• how high the fish is at one second
