But the slope is still positive. The slope is still positive all the way until we get right over there. It seems like it gets pretty close to 0. And then the slope gets a negative. And then right over here, the slope is negative. So this is interesting because even though f is actually not differentiable right here, so f is not differentiable at that point right over there. And you can see because the slope goes pretty close to 0, then it just jumps to negative 3.
