Question

A relationship between the sets P and Q. Write this relation in (i) set builder form

(ii) roster form. What is its domain and range ?

Answer 1

(i)Set builder form of the relation from P to Q is

R = {$(x,y):y=x-2,xϵP,yϵQ$}

(ii) Roster form of the relation from P to Q is

R = {(5, 3), (6, 4), (7, 5)}

Domain (R) = {5, 6, 7}

Range (R) = {3, 4, 5}
