1. Identify the values in the set:

A = \{-9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9\}

2. Recognize that these values are all integers from -9 to 9.
3. Express the set in set-builder notation:

A = \{x \in \mathbb{Z} \mid -9 \leq x \leq 9\}

Answer:

A = \{x \in \mathbb{Z} \mid -9 \leq x \leq 9\}
