फलन (f(x)=\frac{\sqrt{x-3}}{\sqrt{7-x}}) का प्रांत चुनिए।
Choose the domain of (f(x)=\frac{\sqrt{x-3}}{\sqrt{7-x}}).
Explanation opens after your attempt
Correct Answer
A. ([3,7))
Concept
For the numerator square root \(x-3\ge 0\), and for the denominator square root (7-x>0). Thus \(x\in[3,7\)).
Why this answer is correct
The correct answer is A. ([3,7)). For the numerator square root \(x-3\ge 0\), and for the denominator square root (7-x>0). Thus \(x\in[3,7\)).
Exam Tip
ऊपर के वर्गमूल के लिए \(x-3\ge 0\) और हर के वर्गमूल के लिए (7-x>0) चाहिए। अतः \(x\in[3,7\))।
