So this, we could say, is plus the natural log of the absolute value of x. It's not a bad habit to do it, and if everything's positive, well, the absolute value of x is equal to x. And so what is this going to be equal to? This is equal to, let's evaluate everything at four. And actually, before I even evaluate at four, what's six divided by negative two? That's negative three. So if we evaluate it at four, it's going to be negative three over four squared.
