Question

amy throws a ball in the air. the graph shows the height of the ball on the y - axis and the time that the ball is in the air on the x - axis. the top of the graph is missing. after how many seconds does the ball reach the highest point?

Explanation:

Step1: Observe the graph

The x - axis represents time and the y - axis represents height. The highest point of the ball is the vertex of the parabolic - shaped graph.

Step2: Locate the vertex

By looking at the graph, we find the x - value (time) corresponding to the highest y - value (height). The x - value at the highest point of the upper curve is 2 seconds.

Answer:

2 seconds
