The second derivative test to find extrema
WebJun 15, 2024 · The Second Derivative Test for Extrema is as follows: Suppose that f is a continuous function near c and that c is a critical value of f Then. If f′′ (c)<0, then f has a relative maximum at x=c. If f′′ (c)>0, then f has a relative minimum at x=c. If f′′ (c)=0, then the test is inconclusive and x=c may be a point of inflection. WebThe second derivative test states that if a function has a critical point for which f' (x) = 0, and the second derivative is positive, then the function has a minimum point at that point.

WebMar 26, 2016 · The second derivative is positive (240) where x is 2, so f is concave up and thus there’s a local min at x = 2. Because the second derivative equals zero at x = 0, the Second Derivative Test fails — it tells you nothing about the concavity at x = 0 or whether … WebThe second derivative test can be used to find the local maxima and local minima of a function, under certain constraints.
