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

Let `f(x) = (15 x^2 - 28 x - 32)/(2 x + 3) = ((5 x + 4)(3 x - 8)) / ((2 x + 3))`

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 =
