The height, in feet, of a squirrel running up and down a tree is a function of time, in seconds.

Here are statements describing the squirrel’s movement during four intervals of time. Match each description with a statement about the average rate of change of the function for that interval.

		The average rate of change is large and positive.
		The average rate of change is zero.
		The average rate of change is negative.
		The average rate of change is small and positive.
