چکیده
|
The aim of this paper is to introduce and solve the generalized radical cubic functional equation related to quadratic functional equation f ( 3 √ ax3 + by3 ) + f (3 √ ax3 − by3 ) = 2a² f (x) + 2b² f (y), x, y ∈ r, for a mapping f from r into a vector space. we also investigate some stability and hyperstability results for the considered equation in 2-banach spaces by using an analogue theorem of brzdek in [17].
