In mathematics, an image is a value or set of values of a function. Specifically, let f be a function from the set X to the set Y. If a is an element of X, then its image under f is the value f(a). If A is a subset of X, then its image under f is defined to be f(A) := {f(a) : a in A}. Finally, the image of f itself is f(X), the same as the range of f.
