On a graph, which of the following curve cost starts from Zero?

TVC curve

The correct answer is option 1: TVC curve

TVC (Total Variable Cost) starts from zero.

• At zero output, TVC = 0 because variable costs depend on production.
• As output increases, TVC increases, forming an upward-sloping curve.

  Why not other options?

  2️⃣ AFC Curve (Option 2):

  • AFC = TFC / Q
  • Since TFC is positive, AFC is not defined at Q = 0 and does not start from zero.
  • AFC curve is, in fact, a rectangular hyperbola.

  3️⃣ TFC Curve (Option 3):

  • TFC remains constant regardless of output.
  • Even at Q = 0, TFC has a positive value, meaning it starts above zero.
