Question

If Upper A equals StartSet x | x is an odd integer EndSet commaA={x | x is an odd integer},  Upper B equals StartSet x | x is an even integer EndSet commaB={x | x is an even integer}, Upper C equals StartSet 2 comma 3 comma 4 comma 5 EndSet commaC={2, 3, 4, 5}, and Upper D equals StartSet 13 comma 14 comma 15 comma 16 EndSet commaD={13, 14, 15, 16}, list the​ element(s) of the following set.
C union∪ D

Answer 1

C = {2, 3, 4, 5}    and    D = {13, 14, 15, 16}

C U D = {2, 3, 4, 5, 13, 14, 15, 16}

Answer 2

Answer:

$C\cup D=\{2,3,4,5,13,14,15,16\}$

Step-by-step explanation:

The given set are

$A=\{x|x\text{ is an odd integer}\}$

$B=\{x|x\text{ is an even integer}\}$

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

$D=\{13,14,15,16\}$

We need to find the elements of the set C∪D.

The union of two sets is the set of elements which are in set 1, in set 2, or in both set 1 and set 2.

The union of set C and set D is the set of elements which are in set C, in set D, or in both C and D.

$C\cup D=\{2,3,4,5,13,14,15,16\}$

Hence, $C\cup D=\{2,3,4,5,13,14,15,16\}$.
