Question

The relation shown in the arrow diagram in set builder form is

• A. {(x, y): x is the square of y, x Є P, y Є Q}
• B. {(x, y): y is the square of x, x Є P, y Є Q }
• C. {(x, y), x = 4, 1, y = 2, 1, -1, -2}
• D. {(4, 2), (4, -2), (1, 1), (1, -1)}

Answer 1

The correct option is A

{(x, y): x is the square of y, x Є P, y Є Q}

A relation from set A to set B is a subset of A × B.

Hence, the relation in set builder form is given as

R = {(x, y): x is the square of y, x Є P, y Є Q}
