Explanation:

- TVC (Total Variable Cost) and TFC (Total Fixed Cost):

- TVC starts from zero because variable costs depend on output.

- TFC is constant regardless of output.

- TFC and TVC:

- They do not start from the same point as TFC is fixed and TVC varies based on production.

- TFC (Total Fixed Cost) and TC (Total Cost):

- TFC and TC do start at the same point.

- TFC is always constant and represented on Y-axis when output is zero.

- TC initially overlaps with TFC as TC = TFC when output is zero.

- TFC and AFC (Average Fixed Cost):

- AFC is derived from TFC divided by quantity, hence they don’t start from the same point.
