Is a straight line a one to one function

WebSolution : 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.
