Show that the polynomial has a zero between – 2 and - 1.
X4 - 6x3 - 30x2 + 48x + 82

So, the polynomial has a zero between – 2 and - 1.

Step-by-step explanation:

To find the zeros (or roots) of the polynomial functions, we need to use the remainder theorem and intermediate value theorem.

So here also we will find the value of the polynomial at x=-1 and at x=-2.

So we get:

So here we see that the value of the polynomial at two different values of x, is opposite in sign. So this implies that there must be a zero between – 2 and - 1.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
