, it is significantly more cost-effective than standard textbooks like Munkres [1, 10]. Conciseness
Mendelson’s exercises often ask: Prove or disprove . Here’s how to approach:
"Prove that ( f: X \to Y ) is continuous if and only if for every ( x \in X ) and every neighborhood ( N ) of ( f(x) ), there is a neighborhood ( M ) of ( x ) such that ( f(M) \subset N )."
