Compact sets.) Consider the set A = {-5} U [-3, 2]. Choose one of the three definitions of a compact set that we've studied: via sequences, via closed and bounded sets, or via open covers. (See the Heine-Borel Theorem (Theorem 3.3.6) in the textbook.) Prove that A is compact, using the definition you chose.
