They might be, you know, if this was a constant function, they could just be anything. So we really can't say a lot about them just yet, but they are points of interest. I guess that's all we can say, that they are definitely points of interest. But let's keep going and let's try to understand the concativity and maybe we can get a better sense of this graph. So let's figure out the second derivative. So the second, I'll do that in, let me do it in this orange color. So the second derivative of my function f, let's see, 3 times 12 is 36x squared minus 24x.
