Step 1
Step 1:** The marginal cost function is found by taking the derivative of the total cost function with respect to x: \[MC(x) = \frac{d}{dx} (x^3 + 2x^2 + 2x + 16) = 3x^2 + 4x + 2\] ** Show more…

If the cost function for a commodity is C(x) = 1 90 x3 + 6x2 + 6x + 14 dollars find the marginal cost MC at x = 3 units. (Round your answer to two decimal places.) MC = $ Tell what the marginal cost predicts about the cost of producing 1 additional unit. The cost of producing 1 additional unit is $ . Tell what the marginal cost predicts about the cost of producing 2 additional units. The cost of producing 2 additional units is $ .
Find the marginal cost for producing x units. (The cost is measured in dollars.) C = 225,000 + 9,600x
