A.) y=3x-2 is the correct answer.
The y in the equation simply refers to the y-values in the table.
The x in the equation refers to the x-values in the table.
Plug in each answer like so:
y=3(-2)-2 --> -6-2. Here you do a thing called KFC.
Keep
Flip
Change
You Keep -6
You Change the minus sign in front of the 2 to make it a plus sign
And then you change the positive 2 that is left into a negative 2.
-6+(-2)=-8
If you plug in each of the x-values, you then get the corresponding y-value making option A.) correct.

Bumek [7]

Answer:

$[x - 1][x + 1][{x}^{2} + 4]$

Step-by-step explanation:

Knowing that you have to find two numbers that when they differ to 3, they also multiply to −4, and those numbers are −1 and 4. So, after clearing that up, you will have this [since our degree of this polynomial function is 4]:

$[{x}^{2} - 1][{x}^{2} + 4]$
