3-131.

The graph of is shown at right. Use the graph to list the following values in ascending (increasing) order:

.

means the slope at . Is the slope at positive, negative or zero? How does this compare with the slope at ?

means the slope at . Is the slope at positive, negative or zero? How does it compare with the slope at ?

means the average rate of change between and .
Graphically, this can be seen as the slope of the secant line. Is that slope positive, negative or zero? How does it compare with the slopes at and , and with the value of ?

Looking at the graph from left to right, it is increasing always. The slopes start steep and, as , get smoother.
