Injective in maths
Une application f est dite injective ou est une injection si tout élément de son ensemble d'arrivée a au plus un antécédent par f, ce qui revient à dire que deux éléments distincts de son ensemble de départ ne peuvent pas avoir la même image par f. Lorsque les ensembles de départ et d'arrivée de f sont tous les deux égaux à la droite réelle ℝ, f est injective si et seulement si son graphe intersecte toute droite horizontale en au plus un point. WebbThe injective function can be expressed as an equation or as a set of items. It is a one-to-one function, f (x) = x + 5. This can be understood by considering the function’s domain …

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.)
