That is, the function is both injective and surjective. A bijective function is also called a bijection.

WebWe distinguish two special families of functions: one-to-one functions and onto functions. We shall discuss one-to-one functions in this section. Onto functions were introduced in section 5.2 and will be developed more in section 5.4. WebA function is one-to-one (or injective) if it never assigns two input values to the same output value. Or, said another way, no output value has more than one pre-image. So the above function isn’t one-to-one, because (for example) 4 has more than one pre-image. If we define g : Z → Z such that g(x) = 2x. Then g is one-to-one. 1 ipsec tcam

WebDefinition : A function f : A → B is a bijection if it is one-one as well as onto. In other words, a function f : A → B is a bijection, if it is (i) one-one i.e. f (x) = f (y) x = y for all x, y ∈ A. (ii) onto i.e. for all y ∈ B, there exist x ∈ A such that f (x) = y.
