Sorry, @M4thM1nd but could you help me with this one, too? I just realized that I should probably go to you with this question since it's similar to the last one. What's throwing me off though, is that there are three instead of two now. Wait, does that change anything? Don't  they all have to be equal anyway?

@patricialarios Could you help me, please?

The limit exists if the double sided limit exists, it doesn't matter if it is different at the vertex, if that makes sense

If the left sided limit = the right sided limit, the limit exists. That's a better definition

Thank you so much for helping me out. So if the first (=7) and third (=-63) equations don't agree, then the limit doesn't exist?

Correct there's discontinuity
