Question

The figure shows a relation $R$ between the sets $P$ and $Q$.

The relation $R$ in Set-builder form is

• A. $\{(x,y):x\in P,y\in Q\}$
• B. $\{(x,y):x\in Q,y\in P\}$
• C. $\{(x,y):x$ is the square of $y,x\in P,y\in Q\}$
• D. $\{(x,y):y$ is the square of $x,x\in P,y\in Q\}$

Answer 1

Answer: (C)

It is obvious that the relation $R$ is ' $x$ is the square of $y$ '. In Set-builder form, $R=\{(x,y):x$ is the square of $y,x\in P,y\in Q\}$
