WebHow do you find the points of continuity and the points of discontinuity for a function? Answer: A simple statement can be made as follows: Explanation: The points of continuity are points where a function exists, that it has some real value at that point. WebMay 27, 2024 · Use Theorem 6.2.1 to show that if f and g are continuous at a, then f ⋅ g is continuous at a. By employing Theorem 6.2.2 a finite number of times, we can see that a finite sum of continuous functions is continuous. That is, if f1, f2,..., fn are all continuous at a then ∑n j = 1fj is continuous at a. But what about an infinite sum?
