Answer:
$3,000 (3 from the y-axis)
Step-by-step explanation:
For a relationship to be considered a function, every domain value (x-value) must have exactly one range value (y-value) related to it.
Therefore, for the relationship between age and the value of 12 cars to be considered a function, every age of a car (domain value) must have exactly one particular value in dollars (range value).
From the graph, we can see that age of car of 7 years (x-value/domain value) has two different values of $3,000 and $5,000 (y-value/range value) which doesn't make the the relationship a function.
Therefore, if we remove $3,000 (on the y-axis) from the graph, the relationship will be a function.
We would now have each domain value having exactly one range value.
