For the x-values 1, 2, 3, and do on, the y-values of a function form a geometric sequence that decreases in value. What type of function is it? A. Exponential decay

B. Exponential growth

C. Increasing linear

D. Decreasing linear

A. Exponential decay

Step-by-step explanation:

Since the function decreases in value, it represents a decay, or a decrease.

Also, the function forms a geometric sequence, that is, the product between consecutive values is the same, which is the mark of an exponential function. So the correct option is option A.

(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

the correct answer is 1: 2
