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 ′′. Web12 apr. 2024 · Let’s do one example together.
