Let g(x)=1-lxl.

(a) Evaluate f'(2).

(b) Evaluate f'(-3).

(c) Does f'(0) exist?

For (c) I believe that f'(0) does not exist because it is not locally linear. However for (a) and (b) I do not know how to find f'(of anything). Can someone please explain how to find this and derivatives in general. THANK YOU!
