Can anyone help me solving this problem?

I have tried to set up the mean value theorem, but i just do not know how to proceed.

It is rather obvious even without the mean value theorem. Just multiply and divide by the conjugate.

[tex]\frac{f(b)- f(a)}{b- a}= f'(c)[/tex].

Take f(x)= x

Am I right with my reasoning below: this proves my limit, since lim(f(b)-f(a))=lim(f'(c)*(b-a))=0 since f'(c)=0?
