फलन (f(x)=\sqrt{|x|-3}) का प्रांत क्या है?
What is the domain of (f(x)=\sqrt{|x|-3})?
Explanation opens after your attempt
A. ( \(-\infty,-3]\cup[3,\infty\) )
Concept
The square root needs \(|x|-3\ge 0\). Hence \(|x|\ge 3\), so \(x\le -3\) or \(x\ge 3\).
Why this answer is correct
The correct answer is A. ( \(-\infty,-3]\cup[3,\infty\) ). The square root needs \(|x|-3\ge 0\). Hence \(|x|\ge 3\), so \(x\le -3\) or \(x\ge 3\).
Exam Tip
वर्गमूल के लिए \(|x|-3\ge 0\) चाहिए। इसलिए \(|x|\ge 3\), यानी \(x\le -3\) या \(x\ge 3\)।
