bijective function examples
What conditions must be satisfied for a function to be bijective?
There are some conditions that need to be satisfied for a function to be a bijection. The bijective functions need to satisfy the following four conditions. The element of set A must not be paired with more than one element of set B. The element of set B must not be paired with more than one element of set A.
