Abstract

In this paper, we study the Hyers-Ulam-Rassias stability of the quadratic functional equations for the mapping f from orthogonal linear space in to Banach space. Furthermore, we establish the asymptotic behavior of the above quadratic functional equation. The main result has been supported by well constructed example.
