Abstract : In this paper, we investigate a fuzzy version of stability for the functional equation $$ 2f(x + y) + f(x - y) + f(y-x) - 3f(x) - f(-x) - 3f( y) - f(-y) =0 $$ in the sense of M. Mirmostafaee and M. S. Moslehian.
Keywords : fuzzy normed space, fuzzy almost quadratic-additive mapping, Cauchy additive and quadratic type functional equation
