If Upper A equals StartSet x | x is an even integer EndSet commaA={x | x is an even integer}, Upper B equals StartSet x | x is an odd integer EndSet commaB={x | x is an odd integer}, Upper C equals StartSet 2 comma 3 comma 4 comma 5 EndSet commaC={2, 3, 4, 5}, and Upper D equals StartSet 8 comma 9 comma 10 comma 11 EndSet commaD={8, 9, 10, 11}, list the element(s) of the following set. C union∪ D

C ∪ D = {2, 3, 4, 5, 8, 9, 10, 11}

Step-by-step explanation:

A={x | x is an even integer}

B={x | x is an odd integer},

C={2, 3, 4, 5},

D={8, 9, 10, 11}.

A union of two or more sets is the collection of the members of the sets in a set without repeating any element.

Given sets C and D above, the union of the two sets is the set:

C ∪ D = {2, 3, 4, 5, 8, 9, 10, 11}

Note: The Intersection is the collection of sets that are common to C and D. in this case no element is common, therefore the intersection is a Null Set.
