Web7 de set. de 2016 · No it is not. Explanation: secx = 1 cosx So secx in undefined where cosx = 0, and that happens at odd multiples of π 2, like − π 2 and π 2. secx is undefined at − π 2 and π 2, so it is not continuous on the closed interval, [ − π 2, π 2]. It is continuous on the open interval ( − π 2, π 2). Answer link WebThe derivative of a continuous function f is given. Find the open intervals on which f is (a) increasing: (b) decreasing; and (c) find the x-values of all relative extrema. (a) For which interval/s) is the function increasing?

Web7 de abr. de 2024 · (1) f is continuous on the open interval of (a, b) (2) lim x → a + f (x) = f (a) and (3) lim x → b − f (x) = f (a) In other words, f (x) is continuous on a, b iff it is continuous on (a, b) and it is continuous at a from the right and at b from the left. 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.
