Question

What are the domain and range of each relation?

Drag the answer into the box to match each relation.

Answer 1

Domain = possible X values
Range = possible Y values

Knowing this, it becomes easy...

The blue circles with x and y values -----> (the third option with Domain: -2,0,2,4 Range:-3.-1,0)

The graph below it ----> First box(Domain: -3,-1,0,3 Range: -1,0,1,2,3)

Answer 2

The domain of the first relation is {-2, 0, 2, 4} and the range is {-3, -1, 0}. The domain of the second relation is {-3, -1, 0, 3, 3} and the range is {-1, 0, 1, 2, 3}.

Explanation:

The domain is the set of x-values of a relation. In the mapping on the top left, we have the x-values separated in one section; they are -2, 0, 2 and 4. In the graph on the bottom left, the x-values that have points are -3, -1, 0, 3 and 3 (it is listed twice as it has two points).

The range is the set of y-values of a relation. In the mapping on the top left, we have the y-values separated in one section; they are -3, -1 and 0. In the graph on the bottom left, the y-values that have points are -1, 0, 1, 2 and 3.
