WebFINDING INCREASING OR DECREASING INTERVALS Procedure to find where the function is increasing or decreasing : Find the first derivative. Then set f' (x) = 0 Put solutions on the number line. Separate the intervals. Choose random value from the interval and check them in the first derivative. WebIncreasing and Decreasing Functions Examples. Example 1: Determine the interval (s) on which f (x) = xe -x is increasing using the rules of increasing and decreasing functions. Solution: To determine the interval where f (x) is increasing, let us find the derivative of f (x). f (x) = xe -x. WebSolution: Since f′(x) = 3x2 − 6x = 3x(x − 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, f″ (x) = 6x − 6 , so the only subcritical number is at x = 1 . It's easy to see that f″ is negative for x ... react syntax highlighter typescript
