Question

Identifying the domain and range of the relation.

Answer 1

Domain: {−2,−1,0,1}

Range: {0,2,4}

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! :)
