A vertical line approached by a graph where the function becomes unbounded and is not defined at the corresponding x-value.
A vertical line $x=a$ approached by a graph where the function is undefined and values grow without bound in magnitude.
A vertical line that a graph approaches but does not meet as the function becomes unbounded.
