Question

If R =(-1, 1, 3, 5) and S = (-3, 1, 3), find R u S.(-3,-1, 1, 3, 5, R, S}(-3,-1, 1, 3, 5)(-3,5){}

Answer 1

Given:

`R=\mleft\lbrace-1,1,3,5\mright\rbrace\text{ and S=}\mleft\lbrace-3,1,3\mright\rbrace`

The union of two sets A and B is defined as,

It is set containing all the element that are in A or in B.

So, the union of given two sets is,

`R\cup S=\mleft\lbrace-3,-1,1,3,5\mright\rbrace`
