Stability of generalized QCA-functional equation in P-Banach spaces

In this paper, we investigate the generalized Hyers-Ulam-Rassias stability for the quartic, cubic and additive functional equationf(x+ky)+f(x-ky)=k^۲f(x+y)+k^۲f(x-y)+(k^۲-۱)[k^۲f(y)+k^۲f(-y)-۲f(x)] (k \in \mathbb{Z}-{۰,\pm۱}) in p-Banach spaces.
