Une Application Surjective. Soit f une application de e dans f. The formal definition is the following.
1 soient x et y éléments de a et b et x différent de y x diff. In other words each element of the codomain has non empty preimage. De y donc f x diff de f y car f injective.
Y y x x f x y.
La bijection réciproque est l application g. A surjective function is a surjection. The formal definition is the following. In other words each element of the codomain has non empty preimage.
