MATA31H3 Study Guide - Final Guide: Constant Function, If And Only If, Product Rule
Document Summary
[note] but only the combination of a&b, c&d, the limit exists: horizontal asymptotes: A nonconstant function[1] f has a horizontal asymptotes at y = l if one or both of the following is true. a. limx > f(x) = l, b. limx >- f(x) = l. [note] if f(x) is actually equals to l as x > or as x >- , then we do not consider f has a horizontal asymptotes at y = l. [1]: a constant function f(x) = 1, when x > , f(x) = 1, however f(x) dne horizontal asymptotes: punctured interval: such like (- , 2] u (4, 9, formal definition of limit: limx >c f(x) = l. >0, >0, such that, if 0c f(x) = l and limx >c f(x) = m, then l = m.
