  1. What does the slope of the marginal cost curve portray?
  2. What does the slope of the average variable curve portray?
  3. What does the slope of the average fixed cost curve portray?
  4. What does the marginal cost curve intersect?

1. Marginal cost is upward sloping due to diminishing returns.
 
 
2. Average variable cost also is upward sloping, but is flatter than the marginal cost curve.
 
3. Average fixed cost is downward sloping because of the spreading effect.
 
4. The marginal cost curve intersects the average total cost curve from below, crossing it at its lowest point
