Understanding Increasing, Decreasing, and Constant Functions in Graphs

1. Section 1.5 More on Functions andTheir 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. Find where the graph is increasing? Where is it decreasing? Where is it constant? Example

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

11. Even and Odd Functions and Symmetry
