Well, to minimize this, we would wanna look at the critical points of this, which is where the derivative is either zero or undefined, and see whether those critical points are possibly a minimum or a maximum point. They don't have to be, but those are the ones, if we have a minimum or a maximum point, they're going to be one of the critical points. So let's take the derivative. So the derivative, s prime, let me do this in a different color, s prime of x, I'll do it right over here, actually. The derivative, s prime of x, with respect to x, is going to be equal to 2x times negative 2 times 5, 2x plus 256 times negative 2, so that's minus 512 x to the negative 3 power. X to the negative 3 power. Now, this is going to be undefined, this is going to be undefined when x is equal to zero, but if x is equal to zero, then y is undefined, so this whole thing breaks down.
