We prove the Hyers-Ulam-Rassias stability of the Dav-ison functional equation $f(xy)+f(x+y)=f(xy+x)+f(y)$ for a class of functions from a ring into a Banach space and we also investigate the Davison equation of Pexider type.
Keywords: Hyers-Ulam-Rassias stability, Cauchy equation, Pexider equation, Davison equation
