چکیده
|
We establish the general solutions of the following mixed type of quartic and quadratic functional equation: f(2x+y)+f(2x-y) = 4f(x+y) + 4f(x-y) + 2f(2x) - 8f(x) - 6f(y). moreover we prove the hyers-ulam-rassias stability of this equation under the approximately quartic and the approximately quadratic conditions. copyright © 2014 young-su lee et al.
