Question

9. Using the table below, which statement best describes whether or not the relationship identifies a function? -4 0 1 y -1 1 4 A. The relationship in the table is a function because each y-value is paired with exactly one x-value. B. The relationship in the table is a function because each x-value is paired with exactly one y-value. C. The relationship in the table is not a function because the x-value of O is not paired with y-value of 0. D. The relationship in the table is not a function because each negative x-value is not paired with a positive y-value

Answer 1

Given the table of values:

x y

-4 -1

0 1

1 4

For this set of values to be a function, a single value of x is assigned to one value of y, in other words, no value of x is repeated.

Since no value of x is repeated here, we can say the relationship in the table is a function because each y-value is paired with one x-value.

ANSWER:

A. The relationship in the table is a function because each y-value is paired with exactly one x-value.
