A. x=2, y=0
B. x=2
C. x=2, x=-2
D. x=2, y=1

Respuesta :

The answer is A. Just took the test and got it right. 

Answer:

x=2 is the vertical asymptote.

horizontal asymptote is y=0

Step-by-step explanation:

Find the vertical and horizontal asymptotes

[tex]y=\frac{x^3}{(x-2)^4}[/tex]

To find out the vertical asymptote, we set the denominator =0 and solve for x

[tex](x-2)^4=0[/tex]

Take fourth root on both sides

[tex]x-2=0[/tex]

Add 2 on both sides , so x=2 is the vertical asymptote.

To find horizontal asymptote , we look at the degree of both numerator and denominator

Degree of numerator is 3 and the degree of denominator is 4

When the degree of numerator is less than the degree of numerator then horizontal asymptote is y=0

Here, [tex]3 <4[/tex] so the horizontal asymptote is y=0
