Now, what's the slope of that? Well, the slope of that is 1. So we're going to have a curve that looks like, or a line, I guess we could say, that looks like this. For all x is greater than or equal to 1. So the important thing, remember, we're going to think about the slope of the tangent line when we think about the derivative of g. So slope is equal to 1. And for x less than 1, well, our slope now, if we look right over here, our slope is negative. Our slope is negative 1.
