Question

PLEASE HELPP, DONT SCAM!! The table below represents a function. Which of the following equations could be its function rule?

Answer 1

Explanation:

From the table, let's extract a set of data.

let's take x = 3, y = -9.

Let's substitute x into each of the equation to check.

A.

`y = (x)/( - 3) \\ y = (3)/( - 3) \\ = - 1`

From here we can see the calculated y is not equal to the y in the table, therefore this cannot be the answer.

B.

`y = x \\ y = - 3`

From here we also can see the calculated y is not equal to the y in the table, therefore this also cannot be the answer.

C.

`y = 3x \\ = 3( - 3) \\ = - 9`

From here we can see the calculated y is equal to the y in the table , therefore this is the answer.

D.

`y = - 3x \\ = - 3( - 3) \\ = 9`

From here we can see the calculated y is not equal to the y in the table, therefore this is not the answer.
