Start with the given function
Looking at the numerator

, we can see that the degree is

since the highest exponent of the numerator is

. For the denominator

, we can see that the degree is

since the highest exponent of the denominator is

.
Horizontal Asymptote:
Since the degree of the numerator (which is

) is less than the degree of the denominator (which is

), the horizontal asymptote is always
So the horizontal asymptote is
--------------------------------------------------
Vertical Asymptote:
To find the vertical aysmptote, just set the denominator equal to zero and solve for x

Set the denominator equal to zero

Subtract 40 from both sides

Combine like terms on the right side

Divide both sides by 2 to isolate x

Divide
So the vertical asymptote is
So looking at your answer, you are correct.
