Abstract

In this article, we adopt fixed point method and direct method to find the solution and Intuitionistic fuzzy stability of 3-dimensional cubic functional equation \begin{eqnarray*} g(2u_{1} + u_{2} + u_{3}) &=& 3g(u_{1} + u_{2} + u_{3}) + g( - u_{1} + u_{2} + u_{3}) + 2g(u_{1} + u_{2})+ 2g(u_{1} + u_{3}) -6g(u_{1} - u_{2}) -6g(u_{1} - u_{3}) \\& &\quad- 3g( u_{2} + u_{3}) + 2g(2u_{1} - u_{2}) + 2g(2u_{1} - u_{3}) - 18g(u_{1}) -6g( u_{2}) -6g(u_{3}).\end{eqnarray*}
