Web22 May 2016 · 1 Say we are given the derivative of a function say, f ′ ( x) = { 5 x < 3 − 5 x > 3 Notice that the derivative has opposite signs on either side of x = 3, so you would expect an extrema to occur in f at x = 3 (specifically a maximum in this case), however the derivative is undefined at x = 3, so is there still an extrema? WebExample: Find the concavity of f ( x) = x 3 − 3 x 2 using the second derivative test. DO : Try this before reading the solution, using the process above. Solution: Since f ′ ( x) = 3 x 2 − 6 …

WebIn order to find the inflection point of the function Follow these steps. Take a quadratic equation to compute the first derivative of function f' (x). Now perform the second derivation of f (x) i.e f” (x) as well as solve 3rd derivative of the function. Third derivation of f”' (x) should not be equal to zero and make f” (x) = 0 to find ... Web7 Mar 2013 · Relation with critical points. The second derivative test is specifically used only to determine whether a critical point where the derivative is zero is a point of local maximum or local minimum. Note in particular that: For the other type of critical point, namely that where is undefined, the second derivative test cannot be used.; Since point of local … roger rock campground
