The polynomial function is a cubic polynomial function with a general equation of y = ax^3 + bx^2 + cx + d. a is given to be -1. roots make y = 0
when x = 1
y = -1(1) + b + c + d = -1 +b+c+d = 0
when x = 2
y = -1*8 + 4b + 2c + d = -8 + 4b+c+d = 0
when x =k
y = -k^3 + k^2b + kc + d = 0
when x = 3, y =8
8 = -27 + 9b + 3c + d
<span>b=7/3 , c=23/3 , d=−9
</span>k1<span> = 9.3556</span>
k2<span> = -2.71051</span>
k3<span> = 0.35491</span>

Explanation:</h2>
Hello! Recall that you need to write complete questions in order to get good and precise answers. However, I'll try to explain this problem in a general way. The definition of polynomial functions states:

Suppose we have the following polynomial function:

If
is a factor of this polynomial function, we can write
as:

In whose case:

Evaluating 

So in conclusion:
The graph is shown below and is consistent with our conclusion.

Answer: 12
Step-by-step explanation:
A quarter = 0.25......200 quarters = 200(0.25) = $ 50
a dime = 0.10...150 dimes = 150(0.10) = $ 15
a penny = 0.01....300 pennies = 300(0.01) = $ 3
for a total of : 50 + 15 + 3 = $ 68
