Retrieve the average total cost function given that the total cost=Qsquared+5Q+6

To retrieve the average total cost function, we need to divide the total cost function by the quantity produced (Q). The average total cost (ATC) is calculated by the formula: ATC = Total Cost / Quantity.

Given that the total cost function is Q^2 + 5Q + 6, we can substitute this expression into the formula for ATC:

ATC = (Q^2 + 5Q + 6) / Q

Simplifying further:

ATC = Q / Q + 5 + 6 / Q
ATC = 1 + 5/Q + 6/Q

Therefore, the average total cost function is ATC = 1 + 5/Q + 6/Q.
