Question

if U={1.,2,3,4} and R={(x,y):y>x for all x,y€U} , then find the domain and range of R​

Answer 1

Answer:

Step-by-step explanation:

R={(1,2),(1,3),(1,4),(2,3),(2,4),(3,4)}

Domain = {1,2,3,4}

Range = {2,3,4}

Answer 2

Domain of R:{1,2,3}

Range of R:{2,3,4}

Step-by-step explanation:

U={1,2,3,4}

R={(x,y):y>x for all x, y belongs to U }

Therefore, the relation

R={(1,2),(2,3),(1,3),(1,4),(2,4),(3,4)}

The collection of the values of x  in the relation is called domain and the collection of the values of y in  a given relation is called Range.

Therefore, the domain of R

{1,2,3}

The range of R

{2,3,4}
