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

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.

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”

Example Rel. max= Rel. min= Absolute max= Absolute min= Open intervals of Increasing: Decreasing: Constant:
