यदि (f(x)=x-2-1) और (g(x)=x-2+1) हैं, तो \(\frac{f}{g}\) का डोमेन क्या होगा?
If (f(x)=x-2-1) and (g(x)=x-2+1), what is the domain of \(\frac{f}{g}\)?
Explanation opens after your attempt
A. \( \mathbb{R} \)
Concept
The denominator \(x^2+1\) is never (0), so no real number is excluded. Only real zeros of the denominator are removed.
Why this answer is correct
The correct answer is A. \( \mathbb{R} \). The denominator \(x^2+1\) is never (0), so no real number is excluded. Only real zeros of the denominator are removed.
Exam Tip
हर \(x^2+1\) कभी (0) नहीं होता, इसलिए कोई वास्तविक संख्या हटेगी नहीं। हर को शून्य बनाने वाली वास्तविक संख्या ही हटाई जाती है।
