`f(x)` is a rational function given in both standard and factored forms.

Let `f(x) = (25 x^2 + 60 x + 32)/( x + 9) = ((5 x + 4)(5 x + 8)) / (( x + 9))`

Find:

1) the domain in interval notation  
Note: Use -oo for `-oo`, oo for `oo`, U for union.

2) the y intercept at the point  

3) x intercepts at the point(s)  

4) Vertical asymptotes at x =  

5) Horizontal asymptote at y =
