Identify Any Vertical, Horizontal, or Oblique Asymptotes in the Graph $x = 0$

Identify any vertical, horizontal, or oblique asymptotes in the graph of y = f(x) . State the domain of f.
-

A) Vertical: $x = 0$ ; horizontal: $y = - 4 ; ( - \infty , - 4 ) \cup ( - 4 , \infty )$
B) Vertical: $x = - 4$ ; horizontal: $y = 0 ; ( - \infty , 0 ) \cup ( 0 , \infty )$
C) Vertical: $x = - 4$ ; horizontal: $y = 0 ; ( - \infty , - 4 ) \cup ( - 4 , \infty )$
D) Vertical: $x = 0$ ; horizontal: $y = - 4 ; ( - \infty , 0 ) \cup ( 0 , \infty )$
