elementary set theory - Proving the Cantor Pairing Function Bijective

How would you prove the Cantor Pairing Function bijective? I only know how to prove a bijection by showing (1) If f(x)=f(y), then x=y and (2) There exists an x such that f(x)=y


How would you show that for a function like the Cantor pairing function?
