Does a vertical line pass the vertical line test?

Answer 1

No, a vertical line does not pass the vertical line test.

A vertical line drawn through an existing vertical line has an infinite number of intersections. It only takes 2 or more intersections for a relation to fail the vertical line test.

Answer 2

No, a vertical line does not pass the vertical line test because it intersects the graph of a function at more than one point, violating the condition for a function which states that each input (x-value) can only correspond to one output (y-value).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
