यदि (f(x)=\frac{3}{2-\sqrt{x}}), तो प्रांत क्या है?
If (f(x)=\frac{3}{2-\sqrt{x}}), what is the domain?
Explanation opens after your attempt
Correct Answer
A. \( [0,\infty\)\setminus{4} )
Concept
For \(\sqrt{x}\), \(x\ge 0\), and for the denominator, \(2-\sqrt{x}\ne 0\) is needed. Hence (x=4) is removed.
Why this answer is correct
The correct answer is A. \( [0,\infty\)\setminus{4} ). For \(\sqrt{x}\), \(x\ge 0\), and for the denominator, \(2-\sqrt{x}\ne 0\) is needed. Hence (x=4) is removed.
Exam Tip
\(\sqrt{x}\) के लिए \(x\ge 0\) और हर के लिए \(2-\sqrt{x}\ne 0\) चाहिए। इसलिए (x=4) हटाया जाएगा।
