I think it's safe to assume that it's, and we'll, for the sake of this problem, we're gonna assume that the derivative exists in a neighborhood around x equals eight. So this example, c is eight, so the point eight five is definitely on the curve. The derivative is equal to zero, so we're dealing potentially with one of these scenarios. And our second derivative is less than zero. Second derivative is less than zero. So this threw us, so the fact that the second derivative, so h prime prime of eight is less than zero, tells us that we fall into this situation right over here. So just with the information they've given us, we can say that at the point eight comma five, we have a relative maximum value, or that this is a relative maximum point for this.
