Identifying the domain and range of the relation.

1. The domain is (-2, -1, 0, 1) the rage is (4,2,0,2) 2. It is a function

Step-by-step explanation:

The domain in a pair is always the first number. The range is always the second number in the ordered pair.

Domain: {−2,−1,0,1}

Range: {0,2,4}

Step-by-step explanation:

The domain is all the x-coordinates, but NEEDS TO BE ORDERED, which are {−2,−1,0,1} and you also need to include the curly brackets { }.

The range is all the y-coordinates and also NEEDS TO BE ORDERED, which are {0,2,4} and you also still need to include those curly brackets { }.

Hope this helps and answers your question! :)
