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.

Answer: The range is the set {8, 3, 2, -7} which can be sorted to get {-7, 2, 3, 8}
------------------------------------------------------------------------------
Explanation:
The range is simply the set of possible y values. All you have to do is list all the y coordinates and surround the values in curly braces. The curly braces indicate a set. Every point is of the form (x,y). The y coordinate is the second value listed of each ordered pair.
The method used is Distributive Property.
<h3>What is Distributive property?</h3>
The Distributive Property is an algebraic property that is used to multiply a single value and two or more values within a set of parenthesis.
Given:
(2x² - 1)(3x+2) = (2x²)(3x) + (2x²)(2) + (-1)(3x)+(-1)(2)
Here the property used is Distributive property.
Because distributive property in this way
a*(b+c)= a*b+ a*c
This is how a is being multiplied by with b and c.

You can work it out by using trial and error
so you get
x=3 , y=2
