WebApr 26, 2015 · For example, we might have I = [ 3, ∞) and f ( x) = ( x − 3) 2. Definition 1: The function f is: ( strictly) increasing on I if, for all numbers x 1 < x 2 in I, we have f ( x 1) < f ( x 2). non-decreasing on I if, for all x 1 < x 2 in I, we have f ( x 1) ≤ f ( x 2). Cautions: Some authors use "increasing" to mean "strictly increasing ... WebStep 3 -Test the points from all the intervals. We have got two zeroes or roots that are 1 and -1. These roots show that we have got three intervals that are , , and . We will take the value from each interval and see if it is increasing or decreasing. Lets take -2 from the interval and substitute it in the derivative of a function: 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 ... dominik skauradszun
