Let A = {2, 3, 5} and B = {x, y}. Let p1 and p2 be the projections of A ✕ B onto the first and second coordinates. That is, for each pair (a, b) A ✕ B, p1(a, b) = a and p2(a, b) = b. (a) Find p1(2, y) and p1(5, x). p1(2, y) = p1(5, x) = What is the range of p1? (Enter your answer in set-roster notation.) (b) Find p2(2, y) and p2(5, x). p2(2, y) = p2(5, x) = What is the range of p2? (Enter your answer in set-roster notation.)
