Question

Christopher kicks a football. The graph below shows the height of the football ℎ h in meters after � t seconds. Find the interval for which the football’s height is increasing. 0 Time (in seconds) Height (in meters) t h 0 Time (in seconds) Height (in meters) (1, 4.9) (2, 0)

Answer 1

THE answer is 0≤ t ≤1,

Explanation:

Answer 2

To find the interval in which the height of the football is increasing, we need to find the intervals where the slope of the graph is positive. The slope of the graph gives the rate at which the height is changing.

From the graph, we can see that the height of the football is increasing from 0 to 1 second, and from 4.9 to 5 seconds. At these intervals, the slope of the graph is positive.

Therefore, the interval for which the football's height is increasing is from 0 to 1 second, and from 4.9 to 5 seconds.
