ANSWER
The last graph is the correct answer
EXPLANATION
The function,
is a rational function.
This rational function has a vertical asymptote
at where the denominator is zero.
That is,
This means that, the vertical asymptote occurs at
The graph also has a horizontal asymptote at,
Thus, the horizontal asymptote occurs at
At x-intercept,
This implies that,
The graph cuts the x-axis at,
At y-intercept,
This implies that,
The graph cuts the y-axis at,
The graph that satisfy all the above conditions is the last one.
