And since it's more than 1 half, this whole thing is going to be more than 4, which means this whole thing is going to be positive. So this is negative, this is negative, this is positive. And these are our only candidates for our maximum value. So I would go with this one. Our maximum value happens when x is equal to 2, and that maximum value is 8 natural log of 2 minus 4. That is the absolute maximum value over the interval, I guess we could say over the domain that this function is defined. If we want to verify it with a calculator, we of course could.
