Well once again, x minus one squared, that is defined for all real numbers, it's continuous for all real numbers, so we could just pop that one in there, you get one minus one squared, well that's just zero again. So the left-hand limit, the right-hand limit are both equal zero, which means that the limit is equal, the limit of g of x as x approaches one is equal to zero, which is the same thing as g of one, so we are good with continuity. So we can rule out all the ones that are saying that it's not continuous. So we could rule out that one, and we can rule out that one right over there. So now let's think about whether it is differentiable. So differentiability, so differentiability, I'll write differentiability, ability. Did I, let's see, that's a long word, differentiability.
