Answer:
<h3>A production level that will minimize the average cost of making x items is x=5.</h3>
Step-by-step explanation:
Given that

is the cost of manufacturing x items
<h3>To find a production level that will minimize the average cost of making x items:</h3>
The average cost per item is 
Now we get 
<h3> f(x) is continuously differentiable for all x</h3>
Here x≥0 since it represents the number of items.,
Put x=0 in 
For x=0 the average cost becomes 13000


<h3>∴ f(0)=13000</h3><h3>To find Local extrema :</h3>
Differentiating f(x) with respect to x



<h3>∴ x=5 gives the minimum average cost .</h3><h3>At x=5 the average cost is </h3>


<h3>∴ f(5)=12825 which is smaller than for x=0 is 13000</h3><h3>∴ f(x) is decreasing between 0 and 5 and it is increasing after 5.</h3>
It would be A. because it intercepts the x-axis and y-axis at (0, 0) and D. because it looks like a u
Answer:
C) f(x)=2(25)x
For question 4: f(x)=4()^x
Step-by-step explanation: The correct answer from the choices listed above is option C. IT would be f(x) = 2(25)x that is an equivalent function to f(x) = 2(5)^2x. You can square directly 5 since it will still follow the rules for exponents.
Answer:
answer3
beacuse to find the x-intercept, substitute in 0 for y and solve for x
.
The answer is C.
Hope that helps
