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.

Draggable item		Corresponding Item
The squirrel runs up the tree very fast.		The average rate of change is large and positive.
The squirrel starts and ends at the same height.		The average rate of change is zero.
The squirrel runs down the tree.		The average rate of change is negative.
The squirrel runs up the tree slowly.		The average rate of change is small and positive.

Jada walks to school. The function D gives her distance from school, in meters, as a function of time, in minutes, since she left home.

What does D(10)=0 represent in this situation?

Jada walks to school. The function D gives her distance from school, in meters, t minutes since she left home.

Which equation tells us “Jada is 600 meters from school after 5 minutes”?
