What is the definition of an increasing function?

Back

A function is increasing on an interval if, for any two points x1 and x2 in that interval, if x1 < x2, then f(x1) < f(x2).

How do you determine the intervals where a function is increasing from its graph?

Back

To determine where a function is increasing, look for sections of the graph where the slope is positive (the graph rises as you move from left to right).
