is a real, monotonous function and for all real : . The task is to find all the functions with this property. I have succeeded in showing that the function is strictly monotonous, and trying the linear functions found that only and are solutions and therefore I guess that there are no other solutions but I can't prove it. Any help would be greatly appreciated.
