यदि (f(x)=\frac{x+2}{x-3}) और (g(x)=x-3) हैं, तो ((fg)(4)) क्या होगा?
If (f(x)=\frac{x+2}{x-3}) and (g(x)=x-3), what is ((fg)(4))?
Explanation opens after your attempt
A. (6)
Concept
((fg)(x)=\frac{x+2}{x-3}(x-3)=x+2), where \(x \neq 3\). At (x=4), the value is (6).
Why this answer is correct
The correct answer is A. (6). ((fg)(x)=\frac{x+2}{x-3}(x-3)=x+2), where \(x \neq 3\). At (x=4), the value is (6).
Exam Tip
((fg)(x)=\frac{x+2}{x-3}(x-3)=x+2), जहाँ \(x \neq 3\)। (x=4) पर मान (6) है।
