Question

Relation R in set A = {1, 2, 3 . . . . 13, 14} defined as R = {(x, y): 3x - y = 0}. Write relation in roster form.

• A. R = {(1, 1), (2, 2), (3, 3), (4, 4)}
• B. R = {(1, 2), (2, 4), (3, 6), (4, 8)}
• C. R = {(1, 3), (2, 6), (3, 9), (4, 12)}
• D. R = {(3, 1), (6, 2), (9, 3), (12, 4)}

Answer 1

The correct option is C

R = {(1, 3), (2, 6), (3, 9), (4, 12)}

A = {1, 2, 3 . . . . 13, 14}
R = {(x, y): 3x - y = 0}
Relation R = {(1, 3), (2, 6), (3, 9), (4, 12)}
