Final answer:
The correct relationship between the average cost function Cave(x) and the marginal average cost function Cave'(x) is Cave(x+1) = Cave'(x) + Cave(x).
Step-by-step explanation:
The correct relationship between the average cost function Cave(x) and the marginal average cost function C'ave(x) is:
Cave(x+1) = C'ave(x) + Cave(x)
This means that to estimate the value of the average cost at the next x-value, you add the derivative of the average cost function C'ave(x) to the average cost at the current x-value Cave(x).
