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
Correct Answer

A. \(\mathbb{R}-{-3,2}\)

Step 1

Concept

The product becomes (1), but original denominators give \(x\ne -3,2\). Always decide the domain from the original functions.

Step 2

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.

Step 3

Exam Tip

गुणनफल (1) बनता है, पर मूल हरों से \(x\ne -3,2\) है। डोमेन हमेशा मूल फलनों से तय करें।
