The function f is graphed below. What appears to be the value of the one-sided limit, the limit of f of x, this is f of x, as x approaches negative two from the negative direction? So this is the negative two from the negative direction. So we care what happens as x approaches negative two. We see f of x is actually undefined right over there. But let's see what happens as we approach from the negative direction or as we approach from values less than negative two or as we approach from the left. As we approach from the left, f of negative four is right over here.
