Well, if we're approaching from the left, we're in this scenario right over here. We're to the left of x equals negative one. And so this is going to be equal to the sine, because we're in this case for our piecewise function, of negative one plus one, which is a sine of zero, which is equal to zero. Now what's the two-sided limit as x approaches negative one of g of x? Well, we're approaching two different values as we approach from the right and as we approach from the left. And if our one-sided limits aren't approaching the same value, well, then this limit does not exist. Does not exist.
