Abstract

In this paper, we solve the general solution of a modi¯ed additive and quadratic functional equation f(x + 3y) + 3f(x ¡ y) = f(x ¡ 3y) + 3f(x + y) in the class of functions between real vector spaces and obtain the Hyers-Ulam-Rassias stability problem for the equation in the sense of G¸avrut»a.
