फलन (f(x)=\log_{10}\(4-x^2\)) का प्रांत क्या है?
What is the domain of (f(x)=\log_{10}\(4-x^2\))?
Explanation opens after your attempt
A. ( (-2,2) )
Concept
The logarithm input must satisfy \(4-x^2>0\). Thus \(x^2<4\), so (-2<x<2).
Why this answer is correct
The correct answer is A. ( (-2,2) ). The logarithm input must satisfy \(4-x^2>0\). Thus \(x^2<4\), so (-2<x<2).
Exam Tip
लघुगणक के अंदर \(4-x^2>0\) होना चाहिए। इसलिए \(x^2<4\), यानी (-2<x<2)।
