Some approximations for an equation in modular spaces

In this paper, we introduce and obtain the general solution of a new mixed type quadratic-cubic functional equation. We investigate the stability of such functional equations in the modular space X_\rho by applying \Delta_۲-condition and the Fatou property (in some results) in the modular function \rho.
