<h2>Answer:
</h2>

<h2>Explanation:
</h2>
A quartic function is a function given by the the following equation in standard form:

From the statement we must assume the leading coefficient of f(x) is 11, so:

The zeros are:

So, we can write:



Finally:

Answer:
C(4)=99.5
Step-by-step explanation:
398 divided by 4 is 99.5
4 is the number of sunglasses and therefore equals x.
So C(4)=99.50
This is relatively simple because both have the same common denominator. All you must do is add 3 and 9 together. That gives you 12/14. To simplify we can half both numbers down to 6/7.
