6-137.

While answering the questions below, refer to the graph at right. Assume the axes are scaled equally. ).

1. Between which pair of consecutive points is the average rate of change the greatest?

Average rate of change (AROC) can be seen on a graph as the slope of the secant line between two points.

2. At which point is the instantaneous rate of change closest to $1$?

Instantaneous rate of change (IROC) can be seen on a graph as the slope of the tangent line at a specific point.

3. Which is greater: the average rate of change between $B$ and $C$ or the instantaneous rate of change at $C$?

Which is greater: the slope of the secant line or the slope of the tangent line?

4. Which is greater: the average rate of change between $C$ and $D$ or the average rate of change between $C$ and $E$?

Refer to the previous hints.
