The vertical asymptotes are
No slant asymptote
The horizontal asymptote is
No holes
Explanation:
Let's factorise the denominator
The domain of
As you cannot divide by
The vertical asymptotes are
The degree of the numerator
We calculate the limits of
The horizontal asymptote is
graph{(2x-2)/(x^2-2x-3) [-8.89, 8.89, -4.444, 4.445]}
