The function f : n → z defined by f x x3 is

WebThe set Z of integers is countably infinite. Define f : N → Z by f(n) = (n/2 if n is even; −(n−1)/2 if n is odd. Then f is a bijection from N to Z so that N ∼ Z. If there is no bijection between N and A, then A is called uncountable. Theorem 3.3. There is no surjection from a set A to P(A). Proof. Consider any function f : A → P(A ... Web20 Nov 2016 · This is impossible for the same reason as case 3 is. So f is injective. To prove f is surjective we need to show for all z ∈ Z there is an x ∈ N where f ( x) = z. If z > 0 then 2 …
