For x∈R−{0,1}, let f1(x)=1x, f2(x)=1−x and f3(x)=11−x be three – InterviewSolution

1.	For x∈R−{0,1}, let f1(x)=1x, f2(x)=1−x and f3(x)=11−x be three given functions. If a function, J(x) satisfies (f2∘J∘f1)(x)=f3(x) then J(x) is equal to :
Answer» For $x \in R - {0, 1},$ let $f_{1} (x) = \frac{1}{x}$ , $f_{2} (x) = 1 - x$ and $f_{3} (x) = \frac{1}{1 - x}$ be three given functions. If a function, $J (x)$ satisfies $(f_{2} \circ J \circ f_{1}) (x) = f_{3} (x)$ then $J (x)$ is equal to :
