You can't raise e to any power to get to zero. You try to go to, you know, you could say negative infinity, but that's not, this is not defined. And so if this isn't even defined at x equals three, there's no way that it's going to be continuous at x equals three. So we could rule this one out. Now f of x is equal to e to the x minus three. Well, this is just a shifted over version of e to the x. This is defined for all real numbers, and as we saw in the previous example, it's reasonable to say it's continuous for all real numbers, and you could even do this little test here.
