Answer

{$3,4,5,6,7,8,9$}

Work Step by Step

The question is asking for the union of two sets, in other words it is asking you to find a set that will contain all the elements of one set and all the elements from the other set, without duplicates. If set A contains {$3,4,5,6,7$} and set B contains {$3,7,8,9$} and you are to find the union of set A and B, the answer would be {$3,4,5,6,7,8,9$}. All the elements of this set are either part of A or B or both (notice how 3 is an element they both have in common, but in the unified set it is written only once).
