फलन (f(x)=\frac{1}{|x|-2}) का प्रांत क्या है?
What is the domain of (f(x)=\frac{1}{|x|-2})?
Explanation opens after your attempt
Correct Answer
A. \( \mathbb{R}\setminus{-2,2} \)
Concept
The denominator must not be zero, so \(|x|-2\ne 0\). This gives \(x\ne -2\) and \(x\ne 2\).
Why this answer is correct
The correct answer is A. \( \mathbb{R}\setminus{-2,2} \). The denominator must not be zero, so \(|x|-2\ne 0\). This gives \(x\ne -2\) and \(x\ne 2\).
Exam Tip
हर शून्य नहीं होना चाहिए, इसलिए \(|x|-2\ne 0\)। इससे \(x\ne -2\) और \(x\ne 2\) मिलता है।
