Bijection

Definition of Bijection: A function f: A → B is bijective if it is both injective and surjective.

Cantor-Bernstein-Schröder Theorem

Grades 11-12

Proof that the Composition of Two Bijections is a Bijection

Analyzing Relations: Injectivity, Surjectivity, and Functions for Sets A={1} and B={1,2,3}

Analyzing Relation g: Injective but Not Surjective

Proving a Function is One-to-One if and Only if it is Onto for Finite Sets |A| = |B|
