यदि (f(x)=|x|) और (g(x)=x) हैं, तो ((f-g)(x)) किस (x) के लिए (0) होगा?
If (f(x)=|x|) and (g(x)=x), for which (x) is ((f-g)(x)) equal to (0)?
Explanation opens after your attempt
A. \(x\ge 0\)
Concept
When \(x\ge 0\), (|x|=x), so (|x|-x=0). For modulus questions, split cases by sign.
Why this answer is correct
The correct answer is A. \(x\ge 0\). When \(x\ge 0\), (|x|=x), so (|x|-x=0). For modulus questions, split cases by sign.
Exam Tip
जब \(x\ge 0\), तब (|x|=x), इसलिए (|x|-x=0)। मापांक वाले प्रश्नों में चिन्ह के आधार पर केस बनाएं।
