Consider $$f(x) = \frac{x^3 - 31 x+ 30 }{x^3 - 9 x^2 - 25 x+ 225 }$$
The domain of the function $f(x)$ in interval notation is: .

Give the real root(s) of $f(x)$ as a comma-separated list:

$f(x)$ has one hole at the point: ( , ).

Give the $x$ values where $f(x)$ has vertical asymptote as a comma-separated list: .

$f(x)$ has a horizontal asymptote at $y=$
