1. Section 2.2 More on Functions and Their Graphs

2. Increasing and Decreasing Functions

4. The open intervals describing where functions increase, decrease, or are constant, use x-coordinates and not the y-coordinates.

5. Example Find where the graph is increasing? Where is it decreasing? Where is it constant?

6. Example Find where the graph is increasing? Where is it decreasing? Where is it constant?

7. Example Find where the graph is increasing? Where is it decreasing? Where is it constant?

8. Relative Maxima And Relative Minima

10. Example Where are the relative minimums? Where are the relative maximums? Why are the maximums and minimums called relative or local?

11. Even and Odd Functions and Symmetry
