Answer

Brief Explanations:

A point of inflection of the graph of a function $y = f(x)$ occurs where the second - derivative $f''(x)$ changes sign. Just because $f''(x)=0$ or is undefined does not necessarily mean there is a point of inflection. A relative extreme of $f''(x)$ is not the condition for a point of inflection of $f(x)$.

Answer:

changes sign
