So we have two critical points or critical values here. And what I'm gonna do is I'm gonna graph them, let's put them on a number line. And let's just think about what g prime is doing in the intervals between the critical points. So let's start at zero, one, two, three, and then let's go to negative one. And we have a critical point at, let me do that in magenta. We have a critical point at x equals zero, right over there. And we have a critical point at x equals two, right over there.
