Consider the function $$f(x)=\frac{3 x + 8}{ (6 x + 3)(9 x + 6)}$$

Find the vertical asymptote(s). If there is more than one vertical asymptote give a list of the $x$-values separated by commas. If there are no vertical asymptotes, type in none.

$x =$

---

If this function has a horizontal asymptote, give its $y$-value. If there is no horizontal asymptote, type in none.

$y =$

---

Find the $x$-intercept(s). If there is more than one $x$-intercept give a list of the $x$-intercepts separated by commas (i.e.: (1,2),(3,4)). If there is no $x$-intercept type in none.

Find the $y$-intercept

Find the domain. Write a comma separated list of all the $x$ values that are not in the domain. If there are no such $x$, type none in the answer blank.
$x \ne$
