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. And since the left and right-handed limits are approaching the same thing, we would say that this limit exists, and it is equal to four. Now let's do this next example, as x approaches one. Well, we'll do the exact same exercise.
