Let A = {1, 2, 3, 4], B = {a, b, c}, C = {x, y, z}. Consider the relations R from A to B and S from B to C as follows:

R = {(1, b), (3, a), (3, b), (4, c)} and S = {(a, y), (c, x), (a, z)}

(i) Draw the diagrams of R and S.

(ii) Find the matrix of each relation R, S (composition) RoS.

(iii) Write R−1

and the composition RoS as sets of ordered pairs​
