Une Application Surjective. La définition d une application surjective est. Equivalently a function is surjective if its image is equal to its codomain.
In other words each element of the codomain has non empty preimage. A synonym for surjective is onto the function f. Y y x x f x y.
Displaystyle forall y in y quad exists x in x quad f x y.
X x3 est une bijection de dans. Soit f une application de e dans f. Z z defined by f n 2 n f n 2n f n 2 n is not surjective. De y donc f x diff de f y car f injective.
