The function is a constant line, so its only asymptote are horizontal, and they are the line itself, i.e.
Explanation:
Unless you misspelled something, this was a tricky exercise: expanding the numerator, you get
This means that your function is this horizontal line:
graph{((x-3)(x+3))/(x^2-9) [-20.56, 19.99, -11.12, 9.15]}
As every line, it is defined for every real number
