A quartic functional equation and its generalized Hyers-Ulam-Rassias stability

Montakarn Petapirak, Paisan Nakmahachalasint

Abstract


In this paper, we study the general solution of the quartic functional equation

$f(3x+y)+f(x+3y)=64f(x)+64f(y)+24f(x+y)-6f(x-y)$

and prove its generalized Hyers-Ulam-Rassias stability.
