A Fixed Point Approach to the Fuzzy Stability of an Additive-Quadratic-Cubic Functional Equation

Using the fixed point method, we prove the generalized Hyers-Ulam stability of the following additive-quadratic-cubic functional equation f(x+2y)+f(x−2y) = 2f(x+y)−2f(−x−y)+2f(x−y)−2f(y−x)+f(2y)+f(−2y)+4f(&#x...
