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
Correct Answer

A. ( (-2,2) )

Step 1

Concept

The logarithm input must satisfy \(4-x^2>0\). Thus \(x^2<4\), so (-2<x<2).

Step 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).

Step 3

Exam Tip

लघुगणक के अंदर \(4-x^2>0\) होना चाहिए। इसलिए \(x^2<4\), यानी (-2<x<2)।
