 - Continuity of a function
 - Which functions are continuous
 - The Intermediate Value Theorem
 - Limit
 - Right- and left-hand limits
 - How a limit may not exist
 - What a limit at infinity is



* Understand *
1. Suppose that f(x) = sin(x^2 + 3).  Find f(1) and f(2).  What do
these in conjunction with the Intermediate Value Theorem tell you?


2. Use a graph to estimate lim {x to 0} { (1-cos(x)) / x}.
