A) $f ( x ) = x + 5 , x \neq 5$ ; vertical asymptotes: none
B) $f ( x ) = x - 5 , x \neq - 5$ ; vertical asymptotes: none
C) $f ( x ) = x - 5 , x \neq 5$ ; vertical asymptotes: none
D) $f ( x ) = x + 5 , x \neq - 5$ ; vertical asymptotes: $x =- 5$
E) $f ( x ) = x - 5 , x \neq 5$ ; vertical asymptotes: $x = 5$
