यदि \(R=\{(1,a),(2,b),(3,c)\}\) है, तो (R) के प्रतिलोम का प्रांत क्या होगा?
If \(R=\{(1,a),(2,b),(3,c)\}\), what will be the domain of \(R^{-1}\)?
Explanation opens after your attempt
Correct Answer
B. ({a,b,c})
Concept
In the inverse relation, second components become first components. Hence the domain of \(R^{-1}\) is the range of (R), which is ({a,b,c}).
Why this answer is correct
The correct answer is B. ({a,b,c}). In the inverse relation, second components become first components. Hence the domain of \(R^{-1}\) is the range of (R), which is ({a,b,c}).
Exam Tip
प्रतिलोम में दूसरे अवयव पहले बन जाते हैं। इसलिए \(R^{-1}\) का प्रांत (R) के परिसर ({a,b,c}) के बराबर है।
