Question

look at this set of ordered pairs: (5, -11) (8, -9) (5, 4) (8, 4) (-4, 9) is this relation a function? yes no

Explanation:

Step1: Identify domain values

Domain values: $5, 8, 5, 8, -4$

Step2: Check for repeated domain values

The value $5$ maps to $-11$ and $4$; $8$ maps to $-9$ and $4$. A function requires each domain value to have exactly one range value.
