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. So we just write six x minus nine. And once again, six x minus nine is defined and continuous for all real numbers, so we can just pop a three in there, and you get 18 minus nine. Well, this is also equal to nine.
