संबंध \(R=\{(x,y):y=\frac{2x-1}{x+1},\ x\in{-3,-2,0,1},\ y\in\mathbb{R}\}\) का परिसर क्या है?
What is the range of \(R=\{(x,y):y=\frac{2x-1}{x+1},\ x\in{-3,-2,0,1},\ y\in\mathbb{R}\}\)?
Explanation opens after your attempt
A. \(\left{\frac{7}{2},5,-1,\frac{1}{2}\right}\)
Concept
At the given inputs, the values are \(\frac{7}{2},5,-1,\frac{1}{2}\). For a finite domain, direct substitution is fastest.
Why this answer is correct
The correct answer is A. \(\left{\frac{7}{2},5,-1,\frac{1}{2}\right}\). At the given inputs, the values are \(\frac{7}{2},5,-1,\frac{1}{2}\). For a finite domain, direct substitution is fastest.
Exam Tip
दिए गए इनपुटों पर मान \(\frac{7}{2},5,-1,\frac{1}{2}\) मिलते हैं। सीमित प्रांत में प्रत्यक्ष प्रतिस्थापन सबसे तेज है।
