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.
