Question

R={(x,y): x and y are integers and xy=2}.Then domain of R

​

Answer 1

Step-by-step explanation:

Given that:-

R={(x,y): x and y are integers and xy=2}

If X=1 and Y=2 then xy=1×2=2

If x=2 and y =1 then xy=2×1=2

If x=-1 and y=-2 then xy=(-1)×(-2)=2

If x =-2 and y=-1 then xy=(-2)×(-1)=2

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