Question

Using a graph to evaluate a limit when the limit of x approaches 0

Answer 1

I'm unsure if the answer would be zero since that's where the limit approaches from left to right on the line (but isnt it undefined if the circle isn't filled in). Or if it would be 6 since that's where there's a filled in circle but it isn't on the line. If someone could explain this basic limit problem to me I'd really be grateful.
