If we approach from the right, it looks like we're approaching one. But it turns out that this limit can still exist, as long as the limit as x approaches negative two from the left of the sum, f of x plus g of x, exists and is equal to the limit as x approaches negative two from the right of the sum, f of x plus g of x. So what are these things? Well, as we approach negative two from the left, f of x is approaching, looks like one, and g of x is approaching three. So it looks like we're approaching one and three, so it looks like this is approaching, the sum is going to approach four. And if we're coming from the right, f of x looks like it's approaching three, and g of x looks like it is approaching one. And so once again, this is equal to four.
