### Solution and Stability of a Mixed Type Cubic and Quartic Functional Equation in Quasi-Banach Spaces

#### Abstract

We obtain the general solution and the generalized Ulam-Hyers stability of the mixed type cubic and quartic functional equation $f(x+2y)+f(x-2y)=4(f(x+y)+f(x-y))-24f(y)-6f(x)+3f(2y)$ in quasi-Banach spaces.
