Abstract: Let R be the set of all real numbers. In the present paper we shall characterize functions f : R -* R which are either linear or have graph contained and dense in the plane or half-plane determined by a linear function. For this purpose we consider functions satisfying certain limitary conditions which are related to the additivity equation but considerably weaker than that.
