WebA function can be one-one and a function can be onto. A function can be one-one and onto both. We can say a function is one-one if every element of a set maps to a unique element of another set. And if codomain of a function and range are exactly the same, then it can be known as onto.

WebSurjection: onto mapping = a function f from a set X to a set Y is surjective (or onto), or a surjection, if for every element y in the codomain Y of f there is at least one element x in the domain X of f such that f (x) = y. It is not required that x be unique; the function f may map one or more elements of X to the same element of Y. WebSurjective and Injective functions are the different names for onto and one-to-one functions, respectively. The primary difference is that onto functions hit all the output …

WebA surjection, or onto function, is a function for which every element in the codomain has at least one corresponding input in the domain which produces that output. A function that is both injective and surjective is called bijective. Wolfram Alpha can determine whether a given function is injective and/or surjective over a specified domain.
