WebSince the domain of f is the union of three intervals, it makes sense that the concavity of f could switch across intervals. We cannot say that f has points of inflection at x = ± 1 as they are not part of the domain, but we must still consider these x -values to be important and will include them in our number line. We need to find f ′ and f ′′. WebIf f″(x) changes sign, then ( x, f(x)) is a point of inflection of the function.
