यदि (f(x)=\frac{x+2}{x-3}) और (g(x)=x-3) हों, तो ((fg)(x)) का सरल रूप और डोमेन क्या है?
If (f(x)=\frac{x+2}{x-3}) and (g(x)=x-3), what is the simplified form and domain of ((fg)(x))?
Explanation opens after your attempt
A. (x+2), \(x\ne 3\)
Concept
Multiplication gives (x+2), but \(x\ne 3\) remains because of (f(x)). Always check the original function conditions.
Why this answer is correct
The correct answer is A. (x+2), \(x\ne 3\). Multiplication gives (x+2), but \(x\ne 3\) remains because of (f(x)). Always check the original function conditions.
Exam Tip
गुणन से (x+2) मिलता है, लेकिन (f(x)) के कारण \(x\ne 3\) रहेगा। मूल फलन की शर्तें हमेशा जांचें।
