" Wanted solutions to f ( (3x- 5) / (x +1) ) = 1/ f (x) ; x , f real "




f(x) is not a constant function .

Once more a functional equation ?
YES,but this one does request I believe other
methods than causal process, Abel counting functions
phi(x)on R such as phi((3x- 5)/(x +1)) = phi(x) + 1,
or continuously iterated fonctions.

I would like to know your ideas on this matter.
