Second Derivative Calculator with Steps, Formula and Solution

WebSo, to know the value of the second derivative at a point (x=c, y=f (c)) you: 1) determine the first and then second derivatives. 2) solve for f" (c) e.g. for the equation I gave above f' (x) = 0 at x = 0, so this is a critical point. f" (0) = 6•0 - 2 = -2. Therefore, f (x) is concave downward at x=0 and this critical point is a local maximum.
