So this is going to be five times two to the fourth plus six times two squared, six times two squared, minus two times two, minus two times two. And this is going to be equal to, let's see, two to the fourth power is 16, 16 times five is 80, so that's 80. And then this is six times four, which is 24. And then we are going to subtract four. So this is 80 plus 24 is 104, minus four is equal to 100. So when x is equal to two, this curve is really steep. The slope is 100.
