Answer:
Graph on the top right.
Step-by-step explanation:
A function is a relation where one domain value is assigned to exactly one range value.
In a table, there would be no values repeating in the x-column.
The graph on the top right does not repeat any x values. Therefore, it is a function.
Why the other options are not functions:
- The top left graph has 4 for all it's domain values.
- The bottom left graph has '-2' repeating for the domain.
- The graph on the bottom right repeats '0' as the domain.
Hope this helps.
