Question: A = {1, 2, 3}, B = {4, 5}, C = {a, b, c, d}, R = {(1, b), (2, a), (2, b), (2, c),

  1. A = {1, 2, 3}, B = {4, 5}, C = {a, b, c, d}, R = {(1, b), (2, a), (2, b), (2, c), (3, d)} and S = {(4, a), (4, d), (5, b), (5, c)}. Note that R is a relation from A to C and S is a relation from B to C.
  2. Find S-1 R. This is a relation from which set to which other set? Justify your solution.
  3. Find R-1 S. This is a relation from which set to which other set? Justify your solution.
