Question

If R = (-1, 0, 1, 2, 4, 5) and S = (4, 5, 6), find A n S.O lO (-1, 0, 1, 2, 4, 5, 6)O (4, 5}O (-1, 0, 1, 4, 5)

Answer 1

Given:

$R=\mleft\lbrace-1,0,1,2,4,5\mright\rbrace\text{ and S}=\mleft\lbrace4,5,6\mright\rbrace$$R\cap S=th\text{e common point in R and S.}$$R\cap S=\mleft\lbrace4,5\mright\rbrace$

Hence the answer is

$R\cap S=\mleft\lbrace4,5\mright\rbrace$
