1 # Bijective 2 3 L2 4 5 **Definition:** For a function to be bijective it must be both [Surjective](Surjective.md) and [Injective](Injective.md). 6 7 This means that each value in the domain maps to a unique value in the codomain (Injective) and each value in the codomain is mapped to at least once (Surjective). 8 9 Note: Another term for a bijection is one-to-one correspondence because injection is sometimes called one-to-one and a surjection is sometimes called onto.
