3. By Graph
Set A is called domain of the relation and set B is the codomain.
Each of the elements in the domain (Set A) is an object. So 1, 2 and 3 are called object.
Each of the elements in the codomain (Set B) is an image. So 3, 4, 5 and 6 are called image.
The set that contains all the images that are matched is the range.
