Answer

Explanation:

Step1: Identify vertex from graph

The vertex of the parabola - shaped graph is the point ((1,4.9)). The (t) - coordinate (x - coordinate) of the vertex is the value of (t) at the maximum height of the ball.

Step2: Determine (t) - coordinate meaning

The (t) - coordinate of the vertex is (1), and it represents the time (in seconds) when the ball reaches its maximum height.

Step3: Determine (h) - coordinate meaning

The (h) - coordinate (y - coordinate) of the vertex is (4.9), and it represents the maximum height (in meters) that the ball reaches.

Answer:

The x - coordinate (or t - coordinate) of the vertex is (1) and represents the time when the ball reaches its maximum height. The y - coordinate (or h - coordinate) of the vertex is (4.9) and represents the maximum height of the ball.
