If `R_(3)={(x,|x|),|x` is a real number } is a releation, then find do – InterviewSolution

1.	If `R_(3)={(x,\|x\|),\|x` is a real number } is a releation, then find domain and range of `R_(3)`
Answer» We have, `R_(3)={(x,\|x\|)x` is real number} Clearly, domain of `R_(3)=R` Since, image of any real number `R_(3)` is positive real number of zero, `:.` Range of `R_(3)=R^(+)uu{0}or (0,oo)`
