WebbSolution : Clearly, f is a bijection since it is both one-one (injective) and onto (surjective). Example : Prove that the function f : Q → Q given by f (x) = 2x – 3 for all x ∈ Q is a bijection. Solution : We observe the following properties of f. One-One (Injective) : Let x, y be two arbitrary elements in Q. Then, So, f is one-one.

WebbA one-to-one function is also called an injection, and we call a function injective if it is one-to-one. A function that is not one-to-one is referred to as many-to-one. The contrapositive of this definition is: A function f: A → B is one-to-one if x1 ≠ x2 ⇒ f(x1) ≠ f(x2) Any function is either one-to-one or many-to-one.

A function is injective (one-to-one) if each possible element of the codomain is mapped to by at most one argument. Equivalently, a function is injective if it maps distinct arguments to distinct images. An injective function is an injection. The formal definition is the following.
