Answer:
B
Step-by-step explanation:
For answer A it is stretching the graph of function f by a factor of 15.
For answer C and D it is changing the function itself and that is not what the question is asking.

Answer: 15x^(7/3) - 8x^(7/4) + x + 9000</h3>
=========================================================
Explanation:
If you know the cost function C(x), to find the marginal cost, we apply the derivative.
Marginal cost = derivative of cost function
Marginal cost = C ' (x)
Since we're given the marginal cost, we'll apply the antiderivative (aka integral) to figure out what C(x) is. This reverses the process described above.

D represents a fixed constant. I would have used C as the constant of integration, but it's already taken by the cost function C(x).
To determine the value of D, we plug in x = 0 and C(x) = 9000. This is because we're told the fixed costs are $9000. This means that when x = 0 units are made, you still have $9000 in costs to pay. This is the initial value. You'll find that all of this leads to D = 9000 because everything else zeros out.
Therefore, we go from this
![C(x) = 15x^{7/3} - 8x^{7/4} + x + D\\\\](https://tex.z-dn.net/?f=C%28x%29%20%3D%2015x%5E%7B7%2F3%7D%20-%208x%5E%7B7%2F4%7D%20%2B%20x%20%2B%20D%5C%5C%5C%5C)
to this
![C(x) = 15x^{7/3} - 8x^{7/4} + x + 9000\\\\](https://tex.z-dn.net/?f=C%28x%29%20%3D%2015x%5E%7B7%2F3%7D%20-%208x%5E%7B7%2F4%7D%20%2B%20x%20%2B%209000%5C%5C%5C%5C)
which is the final answer.
<em>Option:</em>
<em>a. for every 13 dogs, there are 25 cats.
</em>
<em>b. there are twice as many cats as dogs at the shelter.
</em>
<em>c. the shelter has more dogs than cats.
</em>
<em>d. there are 25 animals in the shelter.</em>
Answer:
a. for every 13 dogs, there are 25 cats.
<em></em>
Step-by-step explanation:
Represent Dogs with D and Cats with C;
So;
![\frac{D}{C} = \frac{13}{25}](https://tex.z-dn.net/?f=%5Cfrac%7BD%7D%7BC%7D%20%3D%20%5Cfrac%7B13%7D%7B25%7D)
By comparison:
![D=13](https://tex.z-dn.net/?f=D%3D13)
![C = 25](https://tex.z-dn.net/?f=C%20%3D%2025)
This implies that:
For every 13 D, there are 25 C
Hence: Option A is true
