Proving the sum rule

Show that if each of f and g is a function and S(x) = f(x) + g(x), then S’(x) = f’(x) + g’(x).

Would I use the limit formula

limx->a [f(x)+g(x)] = limx->a f(x) + lim x->a g(x).

I have the option of presenting this problem in front of the class but I’m worried I will not be able to explain it because I still don’t understand how to work the problem out
