Identify the domain and range of the following relation {(3,7),(3,8),(3-2),(3,4),(3,1)}

Respuesta :

domain is {3} and range is {-2,1,4,7,8}
domain is all x values in coordinates and range is all y values in coordinates

Answer:

Domain of the following relation is {3}

and Range = { 7, 8, -2, 4, 1}

Step-by-step explanation:

Let R be the set of relation i.e,

R = {(3, 7), (3, 8) , (3, -2) , (3, 4) , (3,1)}

Let R be a relation from set X to set Y,  then  

*Domain of R: The set of all first components of the ordered pairs belonging to R is;

Dom(R) = {x∈A: (x, y) ∈ R for some y∈ Y}.  

*Range of R: The set of all second components of the ordered pairs belonging to R is;

Range of R = {y ∈ Y: (x, y) ∈R for some x∈X}.  

Then, From the given relation R

The Domain of  R is { 3}  and

the range of R is { 7, 8, -2, 4, 1}
