फलन (f(x)=\sqrt{x-1}+\frac{1}{x-5}) का प्रांत क्या है?
What is the domain of (f(x)=\sqrt{x-1}+\frac{1}{x-5})?
Explanation opens after your attempt
Correct Answer
A. \([1,\infty\)-{5})
Concept
For the square root \(x\ge 1\), and for the denominator \(x\ne 5\) are needed. Hence the domain is \([1,\infty\)-{5}).
Why this answer is correct
The correct answer is A. \([1,\infty\)-{5}). For the square root \(x\ge 1\), and for the denominator \(x\ne 5\) are needed. Hence the domain is \([1,\infty\)-{5}).
Exam Tip
वर्गमूल के लिए \(x\ge 1\) और हर के लिए \(x\ne 5\) चाहिए। इसलिए प्रांत \([1,\infty\)-{5}) है।
