यदि (f(x)=x+1) और (g(x)=x-2-4) हैं, तो \(\frac{f}{g}\) का डोमेन क्या है?
If (f(x)=x+1) and (g(x)=x-2-4), what is the domain of \(\frac{f}{g}\)?
Explanation opens after your attempt
A. \( \mathbb{R}-{-2,2} \)
Concept
We need (g(x)\neq0), and \(x^2-4=0\) gives \(x=\pm2\). In quotient questions, always exclude zeros of the denominator.
Why this answer is correct
The correct answer is A. \( \mathbb{R}-{-2,2} \). We need (g(x)\neq0), and \(x^2-4=0\) gives \(x=\pm2\). In quotient questions, always exclude zeros of the denominator.
Exam Tip
हर जगह (g(x)\neq0) चाहिए, और \(x^2-4=0\) से \(x=\pm2\) मिलते हैं। भाग वाले प्रश्नों में हर के शून्य हमेशा हटाएं।
