A function's derivative may be used to decide if the function is increasing or decreasing at any point in its domain. The function is said to be increasing on I if f′(x) > 0 at each point in interval I. The function is said to be decreasing on I if f′(x) 0 at each point in interval I. Since the derivative is zero or not present only at the function's critical points, it must be positive or negative at all other points where the function exists. To find intervals where a function is increasing or decreasing, first, find domain values where all critical points will occur; then, test all intervals in the function's domain to the left and right of these values to see whether the derivative is positive or negative. If f′(x) > 0, f is increasing on the interval, while f′(x) < 0 indicates that f is decreasing on the interval. This and other data can be used to create a reasonably accurate graph of the function's graph.
