फलन (f(x)=\frac{\sqrt{(x-2)(6-x)}}{x-4}) का प्रांत क्या है?
What is the domain of (f(x)=\frac{\sqrt{(x-2)(6-x)}}{x-4})?
Explanation opens after your attempt
A. ( [2,4)\cup(4,6] )
Concept
For the square root, ((x-2)(6-x)\ge 0), so \(x\in[2,6]\). Because of the denominator, (x=4) is removed.
Why this answer is correct
The correct answer is A. ( [2,4)\cup(4,6] ). For the square root, ((x-2)(6-x)\ge 0), so \(x\in[2,6]\). Because of the denominator, (x=4) is removed.
Exam Tip
वर्गमूल के लिए ((x-2)(6-x)\ge 0), इसलिए \(x\in[2,6]\) है। हर के कारण (x=4) हटेगा।
