et est combinaison linéaire des antécédents d'une base de , donc d'au plus deux vecteurs. The rank–nullity theorem is a theorem in linear algebra, which asserts that the dimension of the domain of a linear map is the sum of its rank (the dimension of its image) and its nullity (the dimension of its kernel). En el ejercicio veremos a qué nos referimos cuando hablamos de NÚCLEO de una aplicación lineal, y lo calcularemos para una aplicación dada.

The image of \(f\) is the set of elements of \(T\) to which the function \(f\) maps, \(\it{i.e.}\), the things in \(T\) which you can get to by starting in \(S\) and applying \(f\).
