comment Can we always multiply some function that is not differentiable everywhere with function that is to obtain differentiable product?
You are right. So in general, we will have that $g = 0$ on the closure (in $(a,b)$) of the points of non-differentiability of $f$.

Added something. If only one of $A$, $B$ is simply connected, $A^c$ and $B^c$ are not homeomorphic.
