And it is also differentiable at that point. Now let's look at another example of a point on a function where we aren't differentiable and we also don't see the local linearity. So for example, let's do the absolute value of x. And let me shift it over a little bit just so that we don't overlap as much. All right. So the absolute value of x minus one, it actually is differentiable as long as we're not at this corner right over here, as long as we're not at the point one comma zero. For any other x value, it is differentiable.
