In other words, every element of the function's codomain is the image of at least one element of its domain. It is not required that x be unique; the function f may map one or more elements of X to the same element of Y.

"Injection" makes sense in a concrete category, namely a category C equipped with a faithful functor F: C → Set: a morphism f is an injection if F ( f) is an injection (equivalently, a monomorphism). Faithful functors always reflect monomorphisms: if F ( f) is a monomorphism, then so is f. The proof is straightforward.
