फलन (f(x)=\frac{x-2-4}{x-2}) का परिसर क्या है?
What is the range of (f(x)=\frac{x-2-4}{x-2})?
Explanation opens after your attempt
Correct Answer
A. \( \mathbb{R}\setminus{4} \)
Concept
For \(x\ne 2\), the function equals (x+2). Thus the value (4), which would occur at (x=2), is not in the range.
Why this answer is correct
The correct answer is A. \( \mathbb{R}\setminus{4} \). For \(x\ne 2\), the function equals (x+2). Thus the value (4), which would occur at (x=2), is not in the range.
Exam Tip
\(x\ne 2\) पर फलन (x+2) के बराबर है। इसलिए (x=2) से मिलने वाला मान (4) परिसर में नहीं आता।
