Document Summary

Before wednesday: watch vid on unit 2, unit 1 webwork. Professor gottesman"s office hours: jeffery hall 518, m 4:50-5:50 and w 3:50-4:50. Math help resource center: jeffery hall room 201 (run by graduate students; very helpful) The course is cumulative; if you don"t understand something don"t just let it be. Classmates are also a great resource when it comes to seeking help! A function is continuous on an interval if the function"s graph has no breaks/holes in that interval. In lamens terms, its graph can be drawn with one penstroke. We say that limx > c f(x) = l if the values of f(x) approach l as x approaches c. If limx >c f(x) = l, then limx >c+ f(x) = l and limx >c- f(x) = l. The value of f(c) doesn"t matter when computing the limit. Write a statement that best describes the function around x = 2. lim f(x) = -1 x >2 f(2) = 1.
