Step-by-step explanation:
1-(-y^2-4y-8)-(-4y^2-6y+3)
Simplify: 3y^2+2y−11
Subtract: 3y^2+2y-11
2. 2x^2y^3z^2*4xy^4x^2
Simplify: 8x^5y^7z^2
Subtract: 8x^5y^7z^2
3. (x-4) (x^2-5x-6)
Simplify: x^3-9x^2+14x+24
Subtract: x^3-9x^2+14x+24
Answer:
A
An educated guess because I really forgot how to do these
a and b: decreasing
b and c: constant
c and d: decreasing
d and e: increasing
