Webba bijection. Proof. We let m be a nonzero real number and let b be a real number and deﬁne f WR ! R by f.x/ D mx Cb for all x in R. We will prove that f is a bijection by proving it is both an injectionand a surjection. To prove that f is an injection, we let x1 and x2 be real numbers (hence, in the domain of f ) and assume that f.x1/ D f.x2/.
