Answer:
D. x = 0; y = -6
Step-by-step explanation:
There is a vertical asymptote at the value of x that makes the denominator zero. That value is x=0. This is sufficient to choose the correct answer.
When x gets large, the term 1/x nears zero, so the value of y nears -6. This is the horizontal asymptote.
vertical asymptote: x = 0; horizontal asymptote: y = -6
