Question

If R = (-1, 1, 3, 5) and S = (-3, 1, 3}, find R u S.O [-3,51O fO (-3, -1, 1, 3, 5}O (-3, -1, 1, 3, 5, R, S}

Answer 1

Given:

$\begin{gathered} R=\mleft\lbrace-1,1,3,5\mright\rbrace \\ S=\mleft\lbrace-3,1,3\mright\rbrace \end{gathered}$

To find:

$R\cup S$

The union of two sets R and S is,

$\begin{gathered} R\cup S=\mleft\lbrace-1,1,3,5\mright\rbrace\cup\mleft\lbrace-3,1,3\mright\rbrace \\ =\mleft\lbrace-3,-1,1,3,5\mright\rbrace \end{gathered}$

Hence, the answer is,

$\lbrace-3,-1,1,3,5\rbrace$
