Simple question:
If I have $\lim_{x \to -3^-}f{(x)}$ and I'm looking at a graph, am I approching -3 from the direction of +$\infty$ to -3 (as in going in the negative direction)? Or am I approaching -3 from the direction of -$\infty$ (as in the positive direction)?
edit: sorry corrected my mistake in the question.
