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. Thanks

Hello, 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
