Stuck on a question which i do not know how to solve. Been trying to teach myself how do it but without any luck. Can some one please explain step by step how to solve the problem so i can try and solve similar problems.

Find the interval of continuity and differentiability of the following function:

f(x) = (\sqrt (x^2 - x)) + (\frac (1 / ln(2x - 1)))
