Webthat g(x) = ⌊x⌋. To show that g is onto, we’re given an output value x and need to ﬁnd the corresponding input value. The simplest choice would be y itself. But a proof writer with a sense of humor might pick y +0.1 instead. Suppose we try to build such a proof for a function that isn’t onto, e.g. f : Z → Z such that f(x) = 3x+2. 8 Web2 de mai. de 2015 · 2 Answers. Therefore g is invertible and hence bijective. Since we were required to prove that g is one-one if and only if g is onto, i.e. g is one-one g is onto. Therefore showing that g is bijective completes our proof.
