That is true. And that is one rationale for thinking that, hey, we must have a maximum point, assuming that our function is continuous, at x equals negative four. So this is true. It is a justification for relative maximum, but it is not calculus-based, and so that's why we can rule this one out. The second derivative has a relative minimum at x equals negative four. Well, it does indeed seem to be true. There's a relative minimum there, but that's not a justification for why this is, why H of negative four, or why we have a relative maximum at x equals negative four.
