The biggest rule for functions in a table is that none of the numbers in the X column are repeating. But for the Y column, it is okay to have repeats.

When you look at the answer choices, you could eliminate B, C, and D because of repeats in the x column.

A IS A FUNCTION because all the numbers in the x column are different

B is NOT A FUNCTION because in the x column, there are 2 3's

C is NOT A FUNCTION because in the x column, there are 2 -5's and 2 -10's

D is NOT A FUNCTION because there are 2 20's

Your answer would be A.

Answer:

(b) –4g^4 – 3g^3 + 4g^2 + 5g + 3

Step-by-step explanation:

The simplification process is described and partially carried out. We are to finish by combining like terms and writing the result in standard form.

<h3>Combine Like Terms</h3>

g^2 + (–4g^4) + 5g + 9 + (–3g^3) + 3g^2 + (–6) . . . . given

The like terms are the g^2 terms and the constants.

= (1 +3)g^2 + (–4g^4) +5g +(9 +(–6)) +(–3g^3)

= 4g^2 +(–4g^4) +5g +3 +(–3g^3)

<h3>Write in Standard Form</h3>

In this form, the terms are written in order of decreasing degree.

= –4g^4 –3g^3 +4g^2 +5g +3
