WebTo prove the right continuity of the distribution function you have to use the continuity from above of P, which you probably proved in one of your probability courses. Lemma. If a sequence of events { A n } n ≥ 1 is decreasing, in the sense that A n ⊃ A n + 1 for every n ≥ 1, then P ( A n) ↓ P ( A), in which A = ∩ n = 1 ∞ A n. Let's use the Lemma. 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?

WebAt x=0 it has a very pointy change! But it is still defined at x=0, because f (0)=0 (so no "hole"), And the limit as you approach x=0 (from either side) is also 0 (so no "jump"), So it is in fact … WebThe function 1/x is not uniformly uniformly continuous. This is because the δ necessarily depends on the value of x. A uniformly continuous function is a one for which, once I specify an ε there is a δ that work for all x and y. For example, the function g (x) = √x is uniformly continuous. Given ε, pick δ = ε 2. Note that √x-√y ≤ ...
