$f(x,y) = z \iff x + y = z.$ – user2661923 Apr 21 '22 at 21:45 — user2661923, Apr 21 '22 at 21:45

Yes. You can consider a function with domain $\mathbb{R}^2$ and range $\mathbb{R}$ for defining this function(note that $\mathbb{R}$ can be replaced by any set closed under addition, how the + is defined. For eg, the set of natural numbers)
