Terms in this set 6 The represent the domain of a function. Domain All of the values that go into a relation or a function are called the domain. Use a comma to separate answers as needed The range for the given relation is.

So each x-value is not matched with only one y-value. Its really just an association sometimes called a mapping between members of the domain and particular members of the range. The domain is the set of all x-values in the relation.

12921 at 7AM For each diagram say whether it is a function and. Write the solution to the given inequality in interval notation. So this relation is not a function.

Lydia Eugene Janet Rick Marty The range is the set of all y-values in the relation. The above list of points being a relationship between certain x s and certain y s is a relation. U U 4 O A.

The range is the set of all y or output values. Because over here you pick any member of the domain and the function really is just a relation. The domain has to do with the values of x in your function.
