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. So it's going to look like this. It's going to look like that. But for the point in question, if we're thinking about g prime of 9, so 9 is someplace out here.
