#### Answer:

None. See the graph and explanation.

#### Explanation:

By actual division,

f = 3+(x-8)/(x^2+1)

y = quotient = 3 and

the factors of the denominator (x+i)(x-i) of the remainder = 0 give

the asymptotes.

The graph is asymptote-inclusive.

So, the only real asymptote is the horizontal asymptote y = 3.

graph{(y(x^2+1)-3x^2-x+5)(y-3)=0 [-20, 20, -10, 10]}

#### Answer:

Your function shouldn't have any vertical asymptote.

#### Explanation:

The vertical asymtote is found at values of
