![## Cost Curves of a Firm
The figure below illustrates the cost curves of a firm.
### Figure 9.2: Cost Curves
**Graph Description:**
- **Axes:**
- The vertical axis represents Cost (in dollars).
- The horizontal axis represents Quantity.
- **Cost Curves:**
- **MC (Marginal Cost):** This curve is upward-sloping, indicating the additional cost of producing one more unit.
- **ATC (Average Total Cost):** This curve is U-shaped, representing the average cost per unit, which is initially high, decreases, and then rises again due to varying efficiencies.
- **AVC (Average Variable Cost):** This curve is also U-shaped but below the ATC curve. It reflects the variable costs per unit and follows a similar pattern to ATC.
**Definitions:**
- **ATC (Average Total Cost):** Total cost divided by the quantity of output produced.
- **AVC (Average Variable Cost):** Variable cost divided by the quantity of output produced.
- **MC (Marginal Cost):** The cost of producing one additional unit of output.
These curves are essential for understanding the firm's cost structure and decision-making regarding production levels.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F478e5f39-343f-4c82-8cfb-ffa79b1b8624%2F76273162-8ecf-4163-be1d-12343cbb117c%2Fbcee1cn.jpeg&w=3840&q=75)
