Consider the function $$f(x)= \frac{(8 x - 8 ) }{(-8 x - 4 ) (2 x - 8 )} .$$ Enter the equations of the vertical asymptotes. If there are no vertical asymptotes, enter none. If there is more than one vertical asymptote, enter a list of the equations separated by a comma (e.g., x=20, x=-7).

Vertical asymptotes:

Enter the equations of the horizontal asymptotes. If there are no horizontal asymptotes, enter none. If there is more than one horizontal asymptote, enter a list of the equations separated by a comma (e.g., y=20, y=-7).
