Abstract

In this article, we unify the system of functional equations defining a multi additive-cubic mapping to obtain a single equation. Using a fixed point theorem, we study the generalized Hyers-Ulam stability of such equation. As a result, we show that the multi-additive-cubic functional equation is hyperstable.
