Analyze how cost curves (MC, AVC, AFC, TC, ATC) behave and how they relate to each other in short-run production.

Determine the stages of production including increasing returns, diminishing returns, and negative returns in the context of the law of diminishing marginal returns.

Calculate total cost, total variable cost, total fixed cost, marginal cost, average variable cost, average total cost, and average fixed cost given necessary data.

Identify the point where the marginal cost curve intersects the average total cost and average variable cost curves, and understand the significance of these intersections.
