फलन (f(x)=\frac{\sqrt{x+1}}{x-2-4}) का प्रांत क्या है?
What is the domain of (f(x)=\frac{\sqrt{x+1}}{x-2-4})?
Explanation opens after your attempt
Correct Answer
A. \( [-1,\infty\)\setminus{2} )
Concept
The square root needs \(x\ge -1\), and the denominator needs \(x\ne \pm 2\). Since (-2) is already outside the domain, only (2) is removed.
Why this answer is correct
The correct answer is A. \( [-1,\infty\)\setminus{2} ). The square root needs \(x\ge -1\), and the denominator needs \(x\ne \pm 2\). Since (-2) is already outside the domain, only (2) is removed.
Exam Tip
वर्गमूल के लिए \(x\ge -1\) और हर के लिए \(x\ne \pm 2\) चाहिए। (-2) पहले से प्रांत में नहीं है, इसलिए केवल (2) हटेगा।
