Source sentences:
text: An example of a partial function that is injective An example of a function that is not injective.
text: A partial function is said to be injective, surjective, or bijective when the function given by the restriction of the partial function to its domain of definition is injective, surjective, bijective respectively.
text: Because a function is trivially surjective when restricted to its image, the term partial bijection denotes a partial function which is injective.
text: An injective partial function may be inverted to an injective partial function, and a partial function which is both injective and surjective has an injective function as inverse.
