9.The relation R defined in A={1,2,3} by aRb,if $\left|a^2+b^2\right|$$\le$5.Which of the following is false?

R={(1,1)(1,2)(2,1),(2,2)(2,3),(3,2)(3,3)

Now,R={(y,x):(x,y)$\in$R

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

Domain of R={x:(x,y)$\in$R}={1,2,3}

Range of R={y:(x,y)$\in$R}={1,2,3}
