WebDec 27, 2016 · I would like to make use of these components for formulation of a cost function (for data association). Hence, the cost would look something like the following : Cost = A + B + C , where A, B, C could be derived from the quantities I mentioned above (for eg. using variance) or could be any other quantities WebBut your main point is correct: the true "marginal cost" is defined as the true cost of producing one more gallon, so MC = C (101) - C (100), and this would equal the slope of the secant line, since the change in x is 1, so slope = Δy/Δx = Δy/1 = Δy. Indeed, using C' (100) is, as you say, simply an approximation.
