फलन (f(x)=\sqrt{\frac{x-2-4}{9-x-2}}) का प्रांत क्या है?
What is the domain of (f(x)=\sqrt{\frac{x-2-4}{9-x-2}})?
Explanation opens after your attempt
A. (\(-3,-2]\cup[2,3\))
Concept
The condition is \(\frac{x^2-4}{9-x^2}\ge 0\) and \(x\ne -3,3\). A sign chart gives (\(-3,-2]\cup[2,3\)).
Why this answer is correct
The correct answer is A. (\(-3,-2]\cup[2,3\)). The condition is \(\frac{x^2-4}{9-x^2}\ge 0\) and \(x\ne -3,3\). A sign chart gives (\(-3,-2]\cup[2,3\)).
Exam Tip
शर्त \(\frac{x^2-4}{9-x^2}\ge 0\) और \(x\ne -3,3\) है। साइन चार्ट से (\(-3,-2]\cup[2,3\)) मिलता है।
