Answer:
Step-by-step explanation:
How do you tell if a relation is a function using domain and range?
Find the domain by listing all the x values from the relation. Find the range by listing all the y values from the ordered pairs. Repeated values within the domain or range don't have to be listed more than once. In order for a relation to be a function, each x must correspond with only one y value.
which means
There is not a function
because the domain value 10 is paired with both and 10 and 1
and the domain is 10,26,40,56
