To determine which graph represents the function
f(x)=(2x-1)/(x-1) make following steps:

1. The vertical asymptote is
x=1.

2. Simplify the function


f(x)=(2x-1)/(x-1)=(2x-1-1+1)/(x-1)=(2(x-1)+1)/(x-1)=2+(1)/(x-1).

Then the horizontal asymptote is
y=2.

Only option C contains graph with such asymptotes.

Answer: correct choice is C
