A baseball is hit into the air. The height of the baseball, in feet, as a function of time, in seconds, is represented in the graph. In the context of the problem, what is the meaning of (5, 246)?

• The maximum height is 246 feet.

• After 246 seconds, the baseball is 5 feet in the air.

• After 5 seconds, the baseball is 246 feet in the air.

• The baseball hits the ground at 5 seconds.
