Question

question 8 · 2 points
in the relation in the table below, write a value that will make the relation not represent a function.
input |? 2 -4 -2
output | 8 1 4 4

Explanation:

Step1: Recall function definition

A function requires each input maps to one unique output.

Step2: Identify existing inputs

Existing inputs: $2, -4, -2$

Step3: Choose duplicate input

If we set the unknown input to $2$, $-4$, or $-2$, this input will map to two different outputs (e.g., input $2$ would map to $1$ and $8$), violating the function rule.

Answer:

2, -4, or -2
