The typical marginal cost curve will be ______ and the typical average total cost curve will be ______.

Start by identifying the standard shapes for these cost curves in typical microeconomics analysis.
Option 1: 'Upward sloping; U-shaped' — This aligns with the common characterization where marginal cost (MC) rises as output increases due to diminishing marginal returns in production, so MC is generally upward-sloping after some point. The average total cost (ATC) curve is typically U-shaped because ATC falls when output expands due to spreading fixed costs, reaches a minimum, and then rises as variable costs dominate. This option matches the conventional pattern for MC and ATC.
Option 2: 'U-shaped; Downward sloping' — Here MC is described as U-shaped, which is inconsistent with the usual single rising MC after a point; the marginal cost curve is not typically U-shaped in the sense of first falling and then rising in the standard short-run cost framework. Moreover, ATC being downward sloping is incorrect in the long run sense of the standard cost behavior, since ATC is U-shaped rather than constantly declining.
Option 3: 'U-shaped; Upward sloping' — This reverses the expected relationship: MC is not generally U-shaped in the classic sense (it tends to rise after a point rather than follow a U with a distinct minimum like ATC), and ATC being Upward sloping contradicts the typical U-shaped pattern where ATC falls at first.
Option 4: 'Downward sloping; U-shaped' — A downward-sloping MC is not characteristic of the standard short-run production setting, where adding more units tends to increase marginal cost due to diminishing returns. While ATC being U-shaped is correct, pairing it with a downward-sloping MC makes this option incorrect overall.
In summary, only Option 1 coherently matches the textbook depiction: MC is generally upward sloping, and ATC is U-shaped, reflecting fixed costs spread over more output at low levels and variable costs dominating at higher levels.
