Abstract Let $$(X,\bot)$$ be an orthogonality Banach space in the sense of Rätz and $$Y$$ be a Banach space. In this paper, we apply the alternative fixed point theorem for proving the Hyers–Ulam stability of the orthogonally generalized additive-quadratic functional equation of the form $$f(ax+b...
