Let A = {0, 1, 2} and B = {1, 2, 3}. If an element x in A is related to an element y in B iff x = y - 3, which elements x and y are related to each other? (Stated another way: { (x, y) E AxB | x = y - 3}) A. Is the relation defined above a function? Why or why not? B. Define a relation from Z to Z as follows: For all xe Z and all y e Z, x and y are related iff x = y - 3 (Stated another way: {(x, y) e ZxZ|x= y - 3}). Is this relation a function?
