WebbWhen we draw a graph for an injective function, then that graph will always be a straight line. Some more Examples of Injective function: As we have learned examples of … WebbFunctions can be injections ( one-to-one functions ), surjections ( onto functions) or bijections (both one-to-one and onto ). Informally, an injection has each output mapped to by at most one input, a surjection …

The definition of an injection leads us to some imp... eeoc mixed motiveWebbSolution : 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.
