Answer
False
Work Step by Step
If a function gets larger and larger in magnitude without bound as $x$ approaches the number $k$,
then the line \fbox{$x=k$} is a vertical asymptote.
$....................................$
Here, the vertical asymptote is $x=6$,
because the denominator nears zero as x nears 6.
The given line, $y=6$ is horizontal, so it can not be a vertical asymptote.
The statement is false.
