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)
IDK if i have to explain again but
A. (-infinity, infinity)
B. (-infinity, -3]
C. (-infinity, -4)u(-4, 0)u(0, infinity)
those u's are the logic symbol
2. domain: [-6, -1)u(-1, 3]u [3, -infinity)
range: (-infinity, 4]
3a. 8x^2 + 17
3b. 32x^2 + 80x + 53
3c. I cant see the multiplication symbol
<span>-1/11 + 5/11
= 5/11 - 1/11
