Alright, now let's work through this together. So the first thing that is really important to realize is when you see this x approaches one and you see this little negative superscript here, this does not mean approaching negative one. So this does not mean negative one. Sometimes your brain just sees a one and that little negative sign there, and you're like, oh, this must be a weird way of writing negative one, or you don't even think about it. But it's not saying that. It's saying, this is saying, let me put a little arrow here, this is the limit of f of x as x approaches one from the left. From the left.
