WebIf some function f (x) satisfies these criteria from x=a to x=b, for example, we say that f (x) is continuous on the interval [a, b]. The brackets mean that the interval is closed -- that it includes the endpoints a and b. In other words, that the interval is defined as a ≤ x ≤ b. WebAn idea I had was to consider ε > 0, and to note that f is increasing on [a + ε, b − ε]. Then, since limx → af(x) = f(a) and limx → bf(x) = f(b), we can get some contradiction that it's …

Web8 de out. de 2011 · Homework Equations. A function is uniformly continuous provided that whenever {u n } and {v n } are sequences in D such that lim (n→∞) [u n -v n] = 0, then lim (n→∞) [f (u n) - f (v n )] = 0. A function is bounded if there exists a real number M such that f (x) ≤ M for all x in D. Every bounded sequence has a convergent subsequence.
