How do you determine the increasing interval of a function from its graph?

Back

The increasing interval can be determined by identifying the sections of the graph where the function rises as you move from left to right.

Front

How do you determine the decreasing interval of a function from its graph?

Back

The decreasing interval can be determined by identifying the sections of the graph where the function falls as you move from left to right.
