Answer:
12x^2-4x
Step-by-step explanation:
5x + 4x^2 - 9x + 8x^2
Combine like terms
4x^2+8x^2+5x-9x
12x^2-4x
1. If x = -2, then
y = (-2)^2 - 2(-2) - 1
= 4 + 4 - 1
= 7
2. If x = 0, then
y = (0)^2 - 2(0) - 1
= 0 - 0 - 1
= -1
3. If x = 2, then
y = (2)^2 - 2(2) - 1
= 4 - 4 - 1
= -1
4. If x = 3, then
y = (3)^2 - 2(3) - 1
= 9 - 6 - 1
= 2
