Question

Determine the domain and the range of the​ relation, and tell whether the relation is a function.

Answer 1

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

Answer 2

Domain is: {10,26,40,56} and it is not a function
