For any element y as an element of f (A1UA2), there exists an element x element in A1UA2 such that f (x) = y. By the definition of union, x is in A1 or x is in A2. This implies that y is in A1 or y is in A2. Therefore, y is an element of f (A1) or f (A2). Next, let y be an element of f (A1)Uf (A2).
