फलन (f(x)=\sqrt{x+2}+\sqrt{6-x}) का प्रांत क्या है?
What is the domain of (f(x)=\sqrt{x+2}+\sqrt{6-x})?
Explanation opens after your attempt
Correct Answer
A. ([-2,6])
Concept
For both square roots, \(x+2\ge 0\) and \(6-x\ge 0\) are required. Hence \(x\in[-2,6]\).
Why this answer is correct
The correct answer is A. ([-2,6]). For both square roots, \(x+2\ge 0\) and \(6-x\ge 0\) are required. Hence \(x\in[-2,6]\).
Exam Tip
दोनों वर्गमूलों के लिए \(x+2\ge 0\) और \(6-x\ge 0\) चाहिए। इसलिए \(x\in[-2,6]\)।
