To prove a function f is surjective onto you must show that given any element y in the codomain you can produce an element x in the domain such that fx y. All elements in B are used. If for every element of B there is at least one or more than one element matching with A then the function is said to be onto function or surjective function.

The term for the surjective function was introduced by Nicolas Bourbaki. The function fxx1 from the set of integers to itself is onto. Iv and v are not functions.

Is one-to-one injective if maps every element of to a unique element in. X Y be a function. Such a function is called onto or surjective.

Onto Functions Surjective Functions We have noted that there may be an element of the co-domain of a function that is not the image of any element in the domain. The domain of the function that assign to each pair of integers the maximum of these two integers is ___________. In an onto function every possible value of the range is paired with an element in the domain.
