1) a is positive
2) a is negative
3) a is the number zero
4) a is the number one
2- Which function changes from decreasing to increasing at x = -6?
A. y = 3|x+6| - 1
B. y = -2|x+6| + 7
C. y = -1/2|x-6| + 8
D. y = 1/4|x-6| - 3

$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

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
