Question

What are the domain and range of each relation?

Answer 1

Order pairs  given coordinates on the graph: {(−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4)}.

We need to find the domain and range.

Domain of the order pairs are x values of each coordinate and range is the y values of each given coordinate.

Each first value of order pair are the x values and each second value of each order pair are the y values.

In the given coordinates on the graph (−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4), we can see first values are { -3,-1, 1, 4}

and we can see second values are { -4, -1, 1, 4}.

Therefore, Domain : { -3,-1, 1, 4} and

Range : { -4, -1, 1, 4}
