Find all intervals where f x is decreasing
Web3 rows · Increasing/Decreasing test: If f' (x) > 0 on an interval, then f is increasing on that ... WebFrom the graph, we can see that f'(x) is positive on the interval from -4 to -2 and on the interval from 2 to 4. Therefore, the intervals where the graph of f is increasing are: From x=-4 to x=-2; From x=2 to x=4; We can also use the x-intercepts of f'(x) to determine the critical points of f(x), where the increasing or decreasing behavior changes.
