Copyright policy )Stability of a Functional Equation Deriving from Cubic and Quartic Functions
We obtain the general solution and the generalized Ulam‐Hyers stability of the cubic and quartic functional equation 4(f(3x + y) + f(3x − y)) = −12(f(x + y) + f(x − y)) + 12(f(2x + y) + f(2x − y)) − 8f(y)−192f(x) + f(2y) + 30f(2x).
