Intuitionistic fuzzy stability of cubic type mapping

Recently A.Alotaibi, M.Mursaleen , H. Dutta and S.A.Mohiuddine [1] proved the ulam stability of Cauchy functional equation f(x+y)=f(x)+f(y) in the intuitionistic fuzzy normed spaces. S.A.Mohiuddine and A. Alotaib i[2] proved the Fuzzy stability of a cubic functional equation via fixed point technique In this paper we prove the intuitionistic fuzzy stability of cubic functional equation f(2x+y)+f(2x-y)=2f(x+y)+2f(x-y)+12f(x) by using the fixed point alternative.
