Answer:
(a) The average cost function is 
(b) The marginal average cost function is 
(c) The average cost approaches to 95 if the production level is very high.
Step-by-step explanation:
(a) Suppose
is a total cost function. Then the average cost function, denoted by
, is

We know that the total cost for making x units of their Senior Executive model is given by the function

The average cost function is

(b) The derivative
of the average cost function, called the marginal average cost function, measures the rate of change of the average cost function with respect to the number of units produced.
The marginal average cost function is

(c) The average cost approaches to 95 if the production level is very high.

<span>This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0.
If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.</span>
Your answers are c (abc sports) and b ($2,975)
do you need me to explain the math?
The square root 5 is irrational because a square root of a positive number is either an integer or irrational number. Therefore it is irrational.
