Question

The sets e and f are given below

E= (-2, -1,3,5,6,7)
F=(-2,2,6)

what is the intersection of e and f
find the union of e and f
write your answers using set notation

Answer 1

Intersection of two sets E and F is set G which contains elements x that are common to set E and set F.

`G=E\cap F=\{x; x\in E\wedge x\in F\}`

Here G is,

`G=\{-2,6\}`

Union of two sets E and F is a set H which contains all elements x that occur in set E or set F.

`H=E\cup F=\{x; x\in E\vee x\in F\}`

Hence,

`H=\{-2,-1,2,3,5,6,7\}`

Hope this helps.
