फलन (f(x)=\frac{1}{x-2+1}) का वास्तविक प्रांत क्या है?
What is the real domain of (f(x)=\frac{1}{x-2+1})?
Explanation opens after your attempt
A. \(\mathbb{R}\)
Concept
\(x^2+1\) is never (0). Therefore the function is defined for every real (x).
Why this answer is correct
The correct answer is A. \(\mathbb{R}\). \(x^2+1\) is never (0). Therefore the function is defined for every real (x).
Exam Tip
\(x^2+1\) कभी (0) नहीं होता। इसलिए फलन हर वास्तविक (x) पर परिभाषित है।
