यदि (f(x)=\frac{x-2}{x+3}) और (g(x)=\frac{x+3}{x-2}) हों, तो ((fg)(x)) का डोमेन क्या है?
If (f(x)=\frac{x-2}{x+3}) and (g(x)=\frac{x+3}{x-2}), what is the domain of ((fg)(x))?
Explanation opens after your attempt
A. \(\mathbb{R}-{-3,2}\)
Concept
The product becomes (1), but original denominators give \(x\ne -3,2\). Always decide the domain from the original functions.
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{-3,2}\). The product becomes (1), but original denominators give \(x\ne -3,2\). Always decide the domain from the original functions.
Exam Tip
गुणनफल (1) बनता है, पर मूल हरों से \(x\ne -3,2\) है। डोमेन हमेशा मूल फलनों से तय करें।
