AbstractThe Hyers–Ulam stability of the quadratic functional equation (1) on a restricted domain shall be investigated, and the result shall be applied to the study of an asymptotic behavior of that equation. Furthermore, the Hyers–Ulam stability problems of another quadratic equation (4) (on a restricted domain) shall also be treated under the approximately even (or odd) condition, and some asymptotic behaviors of the quadratic mappings and the additive mappings shall be investigated
