यदि (f(x)=\frac{2x+1}{x-1}) और (g(x)=\frac{x-1}{2x+1}) हों, तो ((fg)(0)) का मान क्या है?
If (f(x)=\frac{2x+1}{x-1}) and (g(x)=\frac{x-1}{2x+1}), what is the value of ((fg)(0))?
Explanation opens after your attempt
A. (1)
Concept
(x=0) is in both domains and (f(0)g(0)=(-1)(-1)=1). First check whether the given value is in the domain.
Why this answer is correct
The correct answer is A. (1). (x=0) is in both domains and (f(0)g(0)=(-1)(-1)=1). First check whether the given value is in the domain.
Exam Tip
(x=0) दोनों फलनों के प्रांत में है और (f(0)g(0)=(-1)(-1)=1)। पहले जांचें कि दिया मान प्रांत में है या नहीं।
