    Hey Deci.

    Have you tried differentiating the function to get a DE that you can solve?

    I'm not sure if this helps, but try treating f(1/x) as one function and f(1-x) as another and differentiate twice to get two equations in two unknowns (by differentiating twice) and see if you can solve.

    No, not yet. And I have no idea how to differentiate f(1/x) and f(1-x). How to differentiate those?
