Question

State the domain and range of each relation. Then determine whether the relation is a function.

(6,3)
(10,3)
(-1,3)
(0,3)

Answer 1

See below.

Explanation:

The domain is the set of x-values = {0, -1, 6, 10}.

The range is {3}.

The relation is a function because each element of the domain maps on to only one value of the range.

Answer 2

Domain {-1,0,6,10}

Range: {3}

Yes it's a function.

Explanation:

Domain is all the x's used by your relation. In case of a set of points all you have to do is your list x's. Domain: {-1,0,6 ,10}.

Range is all the y's being used by your relation. In case of a set of points all you have to do is list your y's. Range {3}.

Function: For it be a function no x can be paired with more than one y. Basically all the x's have to be different. In they are in this case so it is a function.
