Increasing and decreasing intervals calculator
Take the derivative of the function. Find the critical values (solve for f ' ( x) = 0) These give us our intervals. Now, choose a value that lies in each of these intervals, and plug them into the derivative. If the value is positive, then that interval is increasing. If the value is negative, then that interval is decreasing. Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative. Figure 3 shows examples of increasing and decreasing intervals on a function.
