WebAn inflection point only requires: 1) that the concavity changes and. 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f" (x) = 0 OR if f" (x) is undefined. An example of the latter situation is f (x) = x^ (1/3) at x=0.
WebIn order for 𝑓(𝑥) to be concave up, in some interval, 𝑓 ''(𝑥) has to be greater than or equal to 0 (i.e. non-negative) for all 𝑥 in that interval. The same goes for 𝑓(𝑥) concave down, but then 𝑓 ''(𝑥) is non-positive. One use in math is that if f"(x) = 0 and f"'(x)≠0, then you do have an inflection … 1) that the concavity changes and 2) that the function is defined at the point.
