On the contrary, suppose ∃(i,j) 𝜖 codomain(Φ 2 ): ∀ x 𝜖domain(Φ 2 ) = ℤ 256 : Φ 2 (x) ≠(i,j), ⇒ The construction of codomain(Φ 2 ) did not add (i,j) into codomain(Φ 2 ), ⇒ At the beginning of construction of codomain(Φ 2 ), codomain(Φ 2 ) ≠ ∅, which contradicts our assumption that codomain(Φ 2 ) = ∅, ⇒ Φ 2 is surjective.Since Φ 2 is injective and surjective, it follows that Φ 2 is bijective.∎ * Medicare Blow to Virtual Colonoscopies * Bone Drugs May Help Fight Breast Cancer * Regimens: Multivitamins Not Found to Reduce Risks * Medicare and 'Off-Label' Cancer Drugs
