Given:

The set R = { -1, 0, 1, 2, 4, 5} and S= { 4, 5, 6}.

Intersection of two set R and S contains all the elements which are common to both set R and S.

[tex]\begin{gathered} R\cap S=\mleft\{-1,0,1,2,4,5\mright\}\cap\mleft\lbrace4,5,6\}\mright? \\ =\mleft\lbrace4,5\mright\rbrace \end{gathered}[/tex]
