If y in f c then y in b and there exists an x in c such that f x y. Given a function f a to b the image of c subseteq a is defined as f c f x mid x in c. In words the image f x of x is the set of all things in b that f sends elements of x to. If y in f c then y in b and there exists an x in c such that f x y.
