Sets A, B, and C are given. Find the indicated set.
A = {-8, -3, -1, 2, 5}, B = {-3, 2, 5, 7}, and C = {-1, 4, 9}
-$( A \cap B ) \cup C$
A) $\{ - 3 , - 1,2 \}$
B) $\{ - 3 , - 1,2,5 \}$
C) $\{ - 3 , - 1,2,4,5,9 \}$
D) $\{ - 3,2,5 \}$

Quizplus · Accepted Answer

First, find the intersection of sets A and B, which is $\{-3, 2, 5\}$. Then, unite this set with set C, resulting in $\{-3, 2, 5\} \cup \{-1, 4, 9\} = \{-3, -1, 2, 4, 5, 9\}$.

Sets A, B, and C Are Given (A∩B)∪C( A \cap B ) \cup C(A∩B)∪C

Sets A, B, and C Are Given $( A \cap B ) \cup C$
