Recall that given f : A → B and subsets X C A respectively Y C B we can define the direct image f(X) C B and the inverse image f'(Y) c A. So that if X C A, then f(X) is a set and if Y C B, then f(Y) is a set; you are proving things about these definitions. Prove that if X c B and Y C B then f'(XUY) =f'(X) U ƒ (Y).
