WebGiven f (x) = x 3, find the inflection point (s). (Might as well find any local maximum and local minimums as well.) Start with getting the first derivative: f ' (x) = 3x 2. Then the second derivative is: f " (x) = 6x. Now set the second derivative equal to zero and solve for "x" to find possible inflection points. 6x = 0.
