Question

The adjoining arrow diagram represents a relation R from set A to set B. Identify the correct statement

• A. Domain of R = {1, 2, 3}
• B. Range of R = {x, y, z}
• C. R = {(1, x), (2, x), (3, x), (2, y)}
• D. Co-domain of R = {x, y}

Answer 1

The correct option is C

R = {(1, x), (2, x), (3, x), (2, y)}

R is a set of ordered pairs where each first element comes from A and each second element comes from B. Hence, the relation can be represented as

R = {(1, x), (2, x), (3, x), (2, y)}
