**How To Find Increasing And Decreasing Intervals On A Graph Calculator**. To find the increasing intervals of a given function, one must determine the intervals where the function has a positive first derivative. To find the an increasing or decreasing interval, we need to find out if the first derivative is positive or negative on the given interval.

Highlight the part of the graph that we are talking about, the section between x = 2 and x = 3. Given the function [latex]p\left(t\right)[/latex] in the graph below, identify the intervals on which the function appears to be increasing. To find these intervals, first find the critical values, or the points at which the first derivative of the function is equal to zero.
