State the domain and the range of each relation. then determine whether the relation is a function.
(4,23)
(3,-2)
(-6,5)
(4,6)

{}

{}

The relation is not a function.

Step-by-step explanation:

By definition, a relation is a function if each input value has only one output value.

Given the relation:

(4,23)

(3,-2)

(-6,5)

(4,6)

The domain is the set of the x-coordinates of each ordered pair (You do not need to write 4 twice):

{}

The range is the set of the y-coordinates of each ordered pair :

 {}

Since the input value 4 has two different output values (23 and 6), the relation is not a function.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
