Assume f: A → B has a left inverse g: B → A, so that g ∘ f = i d . We want to show that f is injective, i.e. that for all x 1, x 2 ∈ A, if f ( x 1) = f ( x 2) then x 1 = x 2. Choose arbitrary x 1 and x 2 in A, and assume that f …

In mathematics, an injective function (also known as injection, or one-to-one function) is a function f that maps distinct elements of its domain to distinct elements; that is, f(x1) = f(x2) implies x1 = x2. (Equivalently, x1 ≠ x2 implies f(x1) ≠ f(x2) in the equivalent contrapositive statement.)
