If f′(x) > 0, then f is increasing on the interval, and if f′(x)

f’(x) is less than 0, then f is decreasing on the interval. This and other information may be used to show a reasonably accurate sketch of the graph of the function. Example 1: For f(x) = x 4 − 8 x 2 determine all intervals where f is increasing or decreasing.
