Best ResponseYou've already chosen the best response.0The relative extrema of a second derivative don't tell you anything about f(x)'s extrema of inflection points

Best ResponseYou've already chosen the best response.0I think so, since zeros of f ' (x) give relative extrema of f(x) and zeros of f " (x) give inflection points.
