And so you're going to be concave upwards, at least at these test values, it looks like on either side of two, that the sign of the second derivative is positive on either side of two. And you might say, well, maybe I just need to find closer values. But if you inspect the second derivative here, you can see that this is never going to be negative. In fact, for any value other than x equals two, this value right over here, since we're, even if x minus two is negative, you're squaring it, which will make this entire thing positive, and then multiplying it times a positive value. So for any value other than x equals two, the sign of our second derivative is positive, which means that we're going to be concave upwards. And so we actually don't have an inflection point at x equals two, because we are not switching signs as we go from values less than x equals two to values greater than x equals two. Our second derivative is not switching signs.
