The function is continuous on (a;b) if fis continuous at each point of (a;b) Note 2 Using one-sided limits we can de ne continuity on closed intervals Note 3 The function is continuous in cif and only if lim x!c f(x) = f(c) Hence all theo-rems about limits apply to continuous functions with L= f(c) It follows directly from Ch 3 1 Theorem 3 :

IIf you know that a function is a function from R to R you might be able to exploit ordering-related properties like the IVT ISimilarly there is additional structure to sequences of real numbers coming from the ordering properties IUsing Taylor’s theorem with remainder can give you quantitative control of how good your approximations are

A function f : E ??R is said to beuniformly continuouson E if for every ?>0 there exists ?>0 such that f(y) ?f(x)
How do you prove that a function is continuous?
- Compositions of continuous functions are continuous. That is, if f is continuous at c, and Gis continuous at f(c), then g(x) = G(f(x)) is continuous at c. Proof. Let x?c. Then f(x) ?f(c), so g(x) = G(f(x)) ?G(f(c)) = g(c): a We now defne continuity and uniform continuity on a set Yof real numbers. Definition 3.12.
What are the properties of continuous functions?
- Properties of Continuous Functions (x3.5{x3.8) 49 a hyperinteger H>0, the closed hyperreal interval [a;b] may be partitioned into subintervals of length = (b a)=H. The partition points are a;a+ ;a+ 2;:::;a+ K;:::;a+ H= b where K runs over the hyperintegers from 0 to H.
What is an injective continuous real function?
- An injective continuous real function f: I ? R on an interval I is strictly monotone. Assume f is injective. That's a contradiction to the assumed c ? ( 0, 1).
