This question refers to unions and intersections of relations. Since relations are subsets of Cartesian products, their unions and intersections can be calculated as for any subsets. Given two relations R and S from a set A to a set B, RUS = {(x, y) EAXB | (x, y) ER or (x, y) ES) Rns={(x, y) EAxBI (x, y) ER and (x, y) E S). Let A = (-2, 2, 5, 7) and B (2, 5) and define relations R and S from A to B as follows: For every (x, y) EA x B, xRylxl = lyl and xSyx-y is even. Using set-roster notation, state explicitly which ordered pairs are in A x B, R, S, RUS, and R n S. (Enter your answers as comma-separated lists of ordered pairs.) AxB= R = S = RUS = Rns=

This question refers to unions and intersections of relations. Since relations are subsets of Cartesian products, their unions and intersections can be calculated as for any subsets. Given two relations R and S from a set A to a set B, RUS = {(x, y) E AXB I (x, y) ER or (x, y) E S} RNS = {(x, y)E AXB| (x, y) ER and (x, y) Es}. Let A = {-2, 2, 3, 5} and B = {2, 3} and define relations R and S from A to B as follows: For every (x, y) E Ax B, x R y - |x| = lyl and xsyex - y is even.
