So let's first think about the limit as we approach from the left-hand side, the limit as x approaches three, as x approaches three from the left-hand side of f of x. Well, when x is less than three, we fall into this case. So f of x is just going to be equal to x squared. And so this is defined and continuous for all real numbers, so we can just substitute the three in there. So this is going to be equal to nine. Now what's the limit of, as we approach three from the right-hand side of f of x? Well, as we approach from the right, this one right over here is, f of x is equal to six x minus nine.
