Answer:
Bottom left
Step-by-step explanation:
The limit as x approaches infinity is 3, so there is a horizontal asymptote at 3. So eliminate top left and bottom right.
Also, the fraction 2/(x-1) is undefined when x=1 (since the denominator is 0), so there is a vertical asymptote at x=1. Eliminate top right
So, your answer is the bottom left graph.
