WebTake 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. WebExample 7: Finding the Intervals of Increase and Decrease of a Rational Function.
