I need help with this problem please, and please make it legible I often can't read it.

2. Suppose that 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 Ato C and S is a relation from B to C. a. Find 8-1 0 R. This is a relation from which set to which other set? Justify your solution. b. Find R-1 O S. This is a relation from which set to which other set? Justify your solution
