फलन (f(x)=\sqrt{x}+\frac{1}{\sqrt{4-x}}) का प्रांत क्या है?
What is the domain of (f(x)=\sqrt{x}+\frac{1}{\sqrt{4-x}})?
Explanation opens after your attempt
A. ( [0,4) )
Concept
For \(\sqrt{x}\), \(x\ge 0\), and for the denominator square root, (4-x>0) is needed. Together, \(0\le x<4\).
Why this answer is correct
The correct answer is A. ( [0,4) ). For \(\sqrt{x}\), \(x\ge 0\), and for the denominator square root, (4-x>0) is needed. Together, \(0\le x<4\).
Exam Tip
\(\sqrt{x}\) के लिए \(x\ge 0\) और हर वाले वर्गमूल के लिए (4-x>0) चाहिए। दोनों मिलाकर \(0\le x<4\) मिलता है।
