Hello,
........|x^4|x^3|x^2|x^1|x^0
........| 1..|.2...|.-9.|.-2.|.8
x=-3.| ....|.-4..|.8..|.4..|.-8
........| 1..|.-2..|.-1.|..2.|.0
x^4+2x^3-9x^2-2x+8=(x+3)(x^3-2x^2-x+2)+0
-4 is a root of the polynomial expression.
Multiplying the two pieces of the function together:
. This is a quadratic function, and since the coefficient of <em>x</em>² is negative we know it is opening downward and thus has a maximum. We can find the maximum by finding the vertex. First we find the axis of symmetry:
. This tell us there will need to be 3 $5 decreases in price, or a $15 decrease, to maximize the function. $50-$15=$35.
We now plug our 3 in for <em>x</em> in our function:
If they decrease the price their total revenue will be $30,625.
Looking at the function we know that they sell an extra 125 yearbooks for every $5 decrease in price. There were 3 $5 decreases, so 3(125) = 375 extra yearbooks. Add this to the original 500 and we have 375+500=875 yearbooks.
Your answer is c hope I helped
