topic 2.4connecting differentiability and continuity
Answer & Explanation
Differentiability and continuity are two fundamental concepts in calculus that
are closely related, yet distinct. Understanding their connection is crucial for
analyzing the behavior of functions.
Key Concepts:
1. Continuity:
o A function ( f(x) ) is continuous at a point ( x = a ) if:
1. ( f(a) ) is defined.
2. The limit of ( f(x) ) as ( x \to a ), denoted as ( \lim_{x \to a}
f(x) ), exists.
3. The limit equals the function value: ( \lim_{x \to a} f(x) =
f(a) ).
