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 slowly.		The average rate of change is large and positive.
The squirrel runs up the tree very fast.		The average rate of change is zero.

Here are four equations of absolute value functions and three coordinate pairs. Each coordinate pair represents the vertex of the graph of an absolute value function.

Match the equation of each function with the coordinates of the vertex of its graph. The vertex coordinates of the graph of one equation are not shown.

Bags of walnuts from a food producer are advertised to weigh 500 grams each. In a certain batch of 20 bags, most bags have an absolute error that is less than 4 grams.

Could this scatter plot represent those 20 bags and their absolute errors? Explain your reasoning.
