Minus, minus 200. And you can just look at inspection that this number right over here is less than four, so this thing right over here is going to be less than 100. You subtract, you subtract 200, so we can write the second derivative at 3.92 is going to be less than zero. You can figure out what the exact value is if you like. So because this is less than zero, we are concave downwards, concave downwards. Another way of saying it is that the slope is, the slope is decreasing the entire time, concave downwards. When the slope is decreasing the entire time, our shape looks like that.
