Question

look at this table:

x	y
-2	20
-19	3
2	8
12	-3

is this relation a function?
options: yes, no

Explanation:

Step1: Recall the definition of a function

A relation is a function if each input (x - value) has exactly one output (y - value).

Step2: Check the x - values in the table

Looking at the table, the x - value of 2 appears twice. When \(x = 2\), we have \(y=3\) and \(y = 8\). This means that the input \(x = 2\) is associated with more than one output.

Answer:

no
