Chapter 7, Problem 7.48(choose chapter or problem)
Let X and Y be sets, let A and B be any subsets of X, and let C and D be any subsets of Y. Determine which of the properties are true for all functions F from X to Y and which are false for at least one function F from X to Y. Justify your answers. For all subsets C and D of Y, F1(C D) = F1(C)F1(D).
