    I'm not sure what you mean. This f(x) is differentiable for all real numbers x.

    Well its a muliple choice, and my options are:

    a. Not differentiable for negative values of X.
    b. Not differentiable for X E (-1, 1)
    c. Not differentiable for x=1 and x=-1
    d. Not differentiable for x=0
