The average cost is minimized at the point where the line going through the origin is tangent to the graph of C(g).

How do you find average cost minimized?

Yes. To summarize: We found the average cost function by dividing the total cost by the number of units produced. Through differentiation, we found the minimum of that function and obtained 60 units as the production level associated with the minimum cost.

At which point the average cost is minimum?

The minimum point on the average variable cost curve is at point m. The firm also has fixed costs, which are independent of the level of output---average fixed costs thus decline continuously as output increases.
