To find the interval for which the ball's height is decreasing, we need to look at the slope of the graph. Since the height is decreasing when the slope of the graph is negative.
Looking at the graph, we can see that the slope is negative from when the ball reaches its peak height and is on its way down. This means that the height is decreasing from the time the ball reaches its peak height until it touches the ground again.
Therefore, the interval for which the ball's height is decreasing is from the peak height until the ball touches the ground again.
