Explanation opens after your attempt
Correct Answer
A. डोमेन \(\mathbb{R}\setminus{-1,1}\) हैDomain is \(\mathbb{R}\setminus{-1,1}\)
Concept
The denominator \(x^2-1\) becomes (0) when \(x=\pm 1\). In exams remove denominator zero values in rational functions.
Why this answer is correct
The correct answer is A. डोमेन \(\mathbb{R}\setminus{-1,1}\) है / Domain is \(\mathbb{R}\setminus{-1,1}\). The denominator \(x^2-1\) becomes (0) when \(x=\pm 1\). In exams remove denominator zero values in rational functions.
Exam Tip
हर \(x^2-1\) तब (0) होता है जब \(x=\pm 1\)। परीक्षा में rational function में denominator zero values हटाएं।
