Cost functions math

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. WebThe cost function for producing light bulbs is shown below. Find the total cost of producing 2 million lightbulbs.
