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

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}

the answer is c. 23/3

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
