This is X, this is the point X comma F of X. Now what's interesting is, where as this expression is the slope of the line connecting X comma F of X and C comma F of C, which is this point, not that point. Remember, we have this removable discontinuity right over here. 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.
