Could someone please confirm if the following functions is differentiable for all x?
I think f(x) is differentiable for all x but not for g(x).
Could someone please confirm ASAP.

I would have answered the same thing...
The functions are both continuous. But if we study the derivatives, we have the same limit for f at x~0, not the same (-1 and 1) for g at x~1
