Answer:
It is A
From the x-value of 3 to the x-value of 8, the y-value goes down from 3 to -6
Answer:

Step-by-step explanation:
![~~~2x^3y-2y\\\\=2y(x^3-1)\\\\=2y(x-1)(x^2+x+1)~~~~~~~~~~;[a^3-b^3 = (a-b)(a^2 +ab+b^2)]](https://tex.z-dn.net/?f=~~~2x%5E3y-2y%5C%5C%5C%5C%3D2y%28x%5E3-1%29%5C%5C%5C%5C%3D2y%28x-1%29%28x%5E2%2Bx%2B1%29~~~~~~~~~~%3B%5Ba%5E3-b%5E3%20%3D%20%28a-b%29%28a%5E2%20%2Bab%2Bb%5E2%29%5D)
The initial value is 3 (when x=0), and the multiplier is 2, when x=2. The equation can be written as
.. y = 3*(2^(x/2))
