What is an injective function? |
For every y in the codomain there is most one x in the domain. A horizontal line should intersect the function at most once. |
One to one only |
|
|
What is a subjective function? |
For every y in the codomain there is at least one x in the domain. A horizontal line should intersect the function at least once. |
One to one or many to one |
|
|
What is a bijective function? |
