The tuples of the relations can be of ________ order.

__________ is a specific domain in the relation which has entries of all tuples.

In Fig.5, ordered pairs are _________.2. These ordered pairs constitute a _______.3. The ordered pairs (A, P), (B, R), (C, Q), (E, Q), (D, T), (G, T), (F, U), (H, U)constitute a relation which is also a _____.4. The ordered pairs (B, R), (C, Q), (D, T), (E, S), (E, Q) constitute a _____which is not a _____

Which of the following relations are functions?R1 ={(3, 4),(4, 5),(6, 7),(8, 9)}, R2 ={(3, 4),(4, 5),(6, 7),(3, 9)}, R3 ={(-3, 4),(4, -5),(0, 0),(8, 9)}, R4 ={(8, 11),(34, 5),(6, 17),(8, 19)}

A = {0, 1, 2, 3, 4, 5, 6, 7} ,suppose R and T are Two relations on A such that R = {(x, y) : 2 * x + 3y = 15} ,T= {(x,y):3x+2y in A} Write down R,T and R°T as a set of ordered pairs?

raw the digraphs representing each of the relations.(a) R1 = {(a, a), (a, b), (b, c), (c, b), (c, d), (d, a), (d, b)}(b) R2 = {(1, 2), (1, 3), (1, 4), (2, 1), (2, 3), (2, 4), (3, 1), (3, 2), (3, 4), (4, 1), (4, 2), (4, 3)}(c) R3 = {(2, 4), (3, 1), (3, 2), (3, 4)}
