1. Open intervals of increasing, decreasing & constant functions
X values
(left most point, right most point)
Looking from left to right
Increasing:
Constant:
Decreasing:

2. Relative Maximum & Minimums
Relative Maximums: High point of a curve
Relative Minimum: Low point of a curve
Absolute Maximum: Highest point of the entire function, if it exists.
Absolute Minimum: Lowest point of the entire function, if it exists.

3. Finding relative maximums and minimums with the calculator
1.) Enter function into editor
Get y alone : y=
2.) 2nd trace 3:minimum or 4:maximum
3.) move cursor just to left side of max or min
4.) “enter”
5.) move cursor just to right side
6.) “enter”
7.) guess – “enter”

4. Example Rel. max= Rel. min= Absolute max= Absolute min=
