Injective, Surjective, Bijective
In the function mapping
, the domain is all
values and the range is all
values.
If
implies
, the function is called injective, or one-to-one.
If for any
in the range there is an
in the domain so that
, the function is called surjective, or onto.
If both conditions are met, the function is called bijective, or one-to-one and onto.
