How To Find Increasing And Decreasing Intervals On A Graph Parabola Ideas. From the graph we can see y is increasing on the interval ( −∞,5), and decreasing on (5,∞) let us see if was can establish this same solution analytically. Example 3 graph of parabola given three points find the equation of the parabola whose graph is shown below.

F ( x) = x 3 − 1 2 x. Because there is only one solution, we know the slope goes from increasing to decreasing once, and that's at x = 1.5. Highlight intervals on the domain of a function where it's only increasing or only decreasing.

Differentiate the function with respect to x, we get Then, trace the graph line. To find increasing and decreasing intervals, we need to find where our first derivative is greater than or less than zero. The function appears to be increasing in two intervals:
