यदि (f(x)=x-1) और (g(x)=x+1) हों, तो (\left\(\frac{f}{g}\right\)(x)) का डोमेन क्या है?
If (f(x)=x-1) and (g(x)=x+1), what is the domain of (\left\(\frac{f}{g}\right\)(x))?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}-{-1}\)
Concept
In division, (g(x)\ne 0), so \(x+1\ne 0\) and \(x\ne -1\). The numerator may be zero.
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{-1}\). In division, (g(x)\ne 0), so \(x+1\ne 0\) and \(x\ne -1\). The numerator may be zero.
Exam Tip
भाग में (g(x)\ne 0) चाहिए, इसलिए \(x+1\ne 0\) और \(x\ne -1\)। अंश शून्य हो सकता है।
