Let P = {-12, -9, -8, -3, -1} and Q = {-8}. What is P ∪ Q? Choices: (A){-8} (B){-12, -9, -3, -1} (C){-9, -8, -3, -1} (D){-12, -9, -8, -3, -1}

Identify elements of set P: Identify the elements of set P. P = {-12, -9, -8, -3, -1}Identify elements of set Q: Identify the elements of set Q. Q = {-8}Determine union of sets P and Q: Determine the union of sets P and Q. The union of two sets is the set containing all the elements from both sets, without duplicates. P ∪ Q = {-12, -9, -8, -3, -1} ∪ {-8} Since -8 is already in set P, it does not need to be added again. P ∪ Q = {-12, -9, -8, -3, -1}

Q. Let

P = \{-12, -9, -8, -3, -1\}

and

Q = \{-8\}

. What is

P \cup Q

\newline

Choices:

\newline

(A)

\{-8\}

\newline

(B)

\{-12, -9, -3, -1\}

\newline

(C)

\{-9, -8, -3, -1\}

\newline

(D)

\{-12, -9, -8, -3, -1\}

Identify elements of set P: Identify the elements of set P. $P = \{-12, -9, -8, -3, -1\}$
Identify elements of set Q: Identify the elements of set Q. $Q = \{-8\}$
Determine union of sets $P$ and $Q$ : Determine the union of sets $P$ and $Q$ . The union of two sets is the set containing all the elements from both sets, without duplicates. $P \cup Q = \{-12, -9, -8, -3, -1\} \cup \{-8\}$ Since $-8$ is already in set $P$ , it does not need to be added again. $P \cup Q = \{-12, -9, -8, -3, -1\}$
