So the limit as x approaches one from the left-hand side of f of x plus g of x, what is that going to be equal to? As we approach, so f of x, as we approach one from the left, looks like this is approaching two. I'm just doing this for shorthand. And g of x, as we approach one from the left, looks like it is approaching zero, so this will be approaching two plus zero, which is two. And then the limit as x approaches one from the right-hand side of f of x plus g of x is going to be equal to? Well, for f of x, as we're approaching one from the right-hand side, looks like it's approaching negative one. And for g of x, as we're approaching one from the right-hand side, looks like we're approaching zero again.
