Question

A = {1, 2, 3, 4, 5}. Relation R from A to A by R = {(x, y):y = x + 2}. Find the relation R.

• A. R = {(1, 2), (1, 3), (1, 4), (1, 5)}
• B. R = {(1, 3), (2, 4), (1, 5), (3, 5)}
• C. R = {(1, 3), (2, 4), (3, 5)}
• D. R = {(1, 4), (2, 5), (3, 5)}

Answer 1

The correct option is C

R = {(1, 3), (2, 4), (3, 5)}

y = x + 2

Relation R = {(1, 3), (2, 4), (3, 5)}
