IMAGE

Image

In mathematics, an image is the subset of a function's codomain which is the output of the function on a subset of its domain. Precisely evaluating the function at each element of a subset X of the domain produces a set called the image of X under or through the function. The inverse image or preimage of a particular subset S of the codomain of a function is the set of all elements of the domain that map to the members of S.
