摘要：

In this paper we establish the general solution of the functional equation integral(x + 2y) + integral(x - 2y) + 4 integral(x) = 3[integral(x + y) + integral(x - y)] + integral(2y) - 2 integral(y) and investigate the Hyers-Ulam-Rassias stability of this equation in quasi-Banach spaces. The concept of Hyers-Ulam-Rassias stability originated from Th. M. Rassias' stability theorem that appeared in his paper: On the stability of the linear mapping in Banach spaces, Proc. Amer. Math. Soc. 72 (1978), 297-300.
