12. Let the universal set be \(\mathbb{R}\), the set of all real numbers, and let \(A = \{x \in \mathbb{R} \mid -3 \leq x \leq 0\}\), \(B = \{x \in \mathbb{R} \mid -1 < x < 2\}\), and \(C = \{x \in \mathbb{R} \mid 6 < x \leq 8\}\). Find each of the following:

a. \(A \cup B\)  
b. \(A \cap B\)  
c. \(A^c\)  
d. \(A \cup C\)  
e. \(A \cap C\)  
f. \(B^c\)  
g. \(A^c \cap B^c\)  
h. \(A^c \cup B^c\)  
i. \((A \cap B)^c\)  
j. \((A \cup B)^c\)
