Then we could think about where we are not continuous. Well, we're definitely not continuous where we have this vertical asymptote right over here. So we're not continuous at x equals negative three. We're also not continuous at x is equal to one. And then the last situation where we are not going to be differentiable is where we have a sharp turn, or you could kind of view it as a sharp point on our graph. And I see a sharp point right over there. Notice, as we approach from the left-hand side, the slope looks like a constant, I don't know, it looks like a positive 3 1⁄2.
