Which set of ordered pairs represents a function? O {(7,4), (3,8), (-4,-4), (0,4)}
O {(-8,0), (-5,6), (-8,1), (-6,5)}
O {(-5,1),(3,-7), (2, -4), (2,7)}
O {(4,2), (4, -9), (9, -6), (7,1)}

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
