यदि (f(x)=\frac{1}{x-2-1}) और (g(x)=x+5) हैं, तो ((f-g)(x)) का प्रांत क्या है?
If (f(x)=\frac{1}{x-2-1}) and (g(x)=x+5), what is the domain of ((f-g)(x))?
Explanation opens after your attempt
Correct Answer
A. \(x\ne-1,1\)
Concept
In \(\frac{1}{x^2-1}\), \(x^2-1\ne0\), so \(x\ne\pm1\). The polynomial (g(x)) does not restrict the domain.
Why this answer is correct
The correct answer is A. \(x\ne-1,1\). In \(\frac{1}{x^2-1}\), \(x^2-1\ne0\), so \(x\ne\pm1\). The polynomial (g(x)) does not restrict the domain.
Exam Tip
\(\frac{1}{x^2-1}\) में \(x^2-1\ne0\), इसलिए \(x\ne\pm1\)। बहुपद (g(x)) प्रांत को सीमित नहीं करता।
