The union of sets A and B, denoted $A \cup B$, includes all elements that are in A, in B, or in both. Since A contains $-3, -2, -1$ and B contains $0, 1, 2$, their union includes all these elements, resulting in $\{-3, -2, -1, 0, 1, 2\}$. The intersection of sets A and B, denoted $A \cap B$, includes all elements that are both in A and in B. Since there are no elements common to both A and B, their intersection is the empty set, denoted $\{\}$.
