यदि (f(x)=x-2) और (g(x)=\sqrt{x}) हैं, तो ((f+g)(x)) का प्रांत क्या है?
If (f(x)=x-2) and (g(x)=\sqrt{x}), what is the domain of ((f+g)(x))?
Explanation opens after your attempt
Correct Answer
A. \(x \geq 0\)
Concept
\(x^2\) is defined for all real (x), but \(\sqrt{x}\) needs \(x \geq 0\). The domain of the sum is the intersection.
Why this answer is correct
The correct answer is A. \(x \geq 0\). \(x^2\) is defined for all real (x), but \(\sqrt{x}\) needs \(x \geq 0\). The domain of the sum is the intersection.
Exam Tip
\(x^2\) सभी वास्तविक (x) के लिए परिभाषित है, लेकिन \(\sqrt{x}\) के लिए \(x \geq 0\) चाहिए। योग का प्रांत प्रतिच्छेद है।
