Determine concavity from first derivative
WebThe first derivative test is the process of analyzing functions using their first derivatives in order to find their extremum point. This involves multiple steps, so we need to unpack … WebJul 28, 2015 · Not the first derivative graph. While the conclusion about "a relative maxim [um]" can be drawn, the concavity of the graph is not implied by this information. consider f ′ ( x) = − x sin ( 1 x) for x ≠ 0 and f ′ ( 0) = 0. f has a maximum at x = 0, but is not concave in any neighborhood of x = 0. It is a good hint.
