WebIn mathematical terms, a bijective function f: X → Y is a one-to-one (injective) and onto (surjective) mapping of a set X to a set Y. The term one-to-one correspondence must not be confused with one-to-one function (an injective function; see figures). A bijection from the set X to the set Y has an inverse function from Y to X. WebAlgebraically, we can define one to one function as: function g: D -> F is said to be one-to-one if g (x1) = g (x2) ⇒ x1 = x2 for all elements x 1 and x 2 ∈ D. A one to one function is also considered as an injection, i.e., a function is injective only if it is one-to-one.

WebAn onto function is a function whose image is equal to its codomain. Also, the range and codomain of an onto function are equal. We can also say that function is onto when every y ∈ codomain has at least one pre-image x ∈ domain. Let's go ahead and learn the onto function definition. WebExpert Answer.
