And so this would be, this expression is calculating the slope of that line. And then if X gets even closer to C, well then we're gonna be calculating the slope of that line. If X gets even closer to C, we're gonna be calculating the slope of that line. And so as we approach from the left, as X approaches C from the left, we actually have a situation where this expression right over here is going to approach negative infinity. And if we approach from the right, if we approach with X as large as in C, well this is our X comma F of X. So we have a positive slope. And then as we get closer, it gets more positive.
