摘要：
In this paper, using Brzdek and Ciepliski's fixed point theorems in a 2-Banach space, we investigate approximate solution for the generalized inhomogeneous radical quadratic functional equation of the form here f is a mapping on the set of real numbers, a,bR+ and D(x,y) is a given function. Some stability and hyperstability properties are presented.
