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

Let `f(x) = (5 x^2 + 16 x + 12)/(4 x - 1) = ((5 x + 6)( x + 2)) / ((4 x - 1))`

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 =
