Question

1. Describe each of the following sets explicitly. Then determine how the sets are related to each other: which sets are subsets or proper subsets of each other. A = \{x \in \mathbb{Z} \mid |x| = -x\} B = \{y \in \mathbb{Z} \mid (-y) \in \mathbb{N}\} C = \{n \in \mathbb{Z} \mid n^2 \le n\}

Step 1

In other words, we need to find all integers x such that x = -x. The only integer that satisfies this condition is x = 0. Therefore, set A can be described explicitly as A = {0}. Show more…
