Oh, g prime, g prime, yes, g prime actually does have a relative maximum at zero comma three, but that doesn't tell us anything about whether we're at a relative minimum point at x equals negative three, so I would rule that out. G prime of negative three is equal to zero. So g prime of negative three is equal to zero. So that tells us that the slope of the tangent line of our function is going to be zero right over there, but that by itself is not enough to say that we are at a relative minimum point. For example, I could be at a point that does something like this, where the slope of the tangent line is zero, and then it keeps increasing again, or it does something like this, and it keeps decreasing. So even though you're at a point where the slope of your tangent line is zero, it doesn't mean you're at a relative minimum point, so I would rule that out. G prime crosses the x-axis from below it to above it at x equals negative three.
