A) \[f(y)\]
B) \[2f(y)\]
C) \[\frac{1}{f(y)}\]
D) none of these
Correct Answer: A
Solution :
We have, \[y=f(x)=\frac{x+2}{x-1}\] \[\Rightarrow \] \[y(x-1)=x+2\] \[\Rightarrow \] \[x(y-1)=2+y\] \[\Rightarrow \] \[x=\frac{2+y}{y-1}\] \[\Rightarrow \] \[x=f(y)\]You need to login to perform this action.
