Second derivative test for relative extrema
Web, the second derivative test fails. Thus we go back to the first derivative test. Working rules: (i) In the given interval in f, find all the critical points. (ii) Calculate the value of the functions at all the points found in step (i) and also at the end points. (iii) From the above step, identify the maximum and minimum value of the function, which are said to be absolute … Web26 Feb 2024 · To find local extrema, we use the first an second derivative tests. f (x) = x4 − 2x3. f '(x) = 4x3 −6x2. For the sake of the first derivative test, let's factor this to: f '(x) = …
