In a metric space, prove closure of ( E ) is closed.

Published originally in the 1960s and kept in print by Dover, the book is slender (~200 pages) but dense. It covers: Introduction To Topology Mendelson Solutions

The book is divided into three main parts: In a metric space, prove closure of ( E ) is closed

Let $A \subseteq X$. We need to show that $\overlineA$ is the smallest closed set containing $A$. First, we show that $\overlineA$ is closed. Let $x \in X \setminus \overlineA$. Then, there exists an open neighborhood $U$ of $x$ such that $U \cap A = \emptyset$. This implies that $U \subseteq X \setminus \overlineA$, and hence $X \setminus \overlineA$ is open. Therefore, $\overlineA$ is closed. We need to show that $\overlineA$ is the
