This is a continuous function. So this is going to be the same thing as e to the negative 4 times 0, which is just e to the 0, which is just 1. So this, once again, is equal to 1. So the function is equal to 1 at that point. The limit as we approach from the left is equal to 1. And the limit as we approach from the right is equal to 1. So the function is continuous there.
