Guys please help me :( You currently have an health insurance policy which includes a $500 deductible
and 10% co-insurance. A friend mentions that his health insurance policy has a
$1,000 stop-loss policy he pays at most $1,000 for medical expenses. After an
accident, you are rushed to the emergency room. You incur hospital charges for a
three-day stay following surgery of $12,437.
Which policy costs you less overall? Calculate the costs of each plan to justify
your answer.

55? i think maybe

step-by-step explanation:

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
