What are the vertical and horizontal asymptotes of f(x)=2x/x-1
a. horizontal asymptote at y = 0, vertical asymptote at x = 1
b. horizontal asymptote at y = 2, vertical asymptote at x = 1
c. horizontal asymptote at y = 1, vertical asymptote at x = 0
d. horizontal asymptote at y = 1, vertical asymptote at x = 2

Find the vertical and horizontal asymptotes of the graph of the function

1. Vertical asymptote.

Since the denominator of the fraction is then the vertical asymptote is because the domain of the function is

2. Horizontal asymptote.

Rewrite the function f(x):

The horizontal asymptote has the equation

correct choice is B
