Question

find the inverse f(x)= 2x+1/x-1

Answer 1

solve for x in terms of f(x)..

that'll be the inverse..
interchange x and f(x)

Answer 2

ok so x=2y+1/y-1?

Answer 3

how are you by the way, long time..you are never on fb lol @shubhamsrg

Answer 4

\[y= \frac{ 2x+1 }{ x-1 }\]
change x for y then make y the subject.
\[x= \frac{ 2y+1 }{ y-1 }\]
\[(y-1)x=2y+1\]
\[xy-x=2y+1\]
\[xy-2y=1+x\]
\[y(x-2)=1+x\]\[y=\frac{ 1+x }{ x-2 }\]
so that is the answer
