Topics
We went over the exercises from Exam #2, and used these to introduce the remaining topics we will be covering:

In particular we discussed linear approximation, using #4 on the exam:

We also started solving for the critical points of the function in #4, i.e., the points where f'(x) = 0:

These critical points, and information about the sign of f(x), will give us information about the shape of the graph y= f(x), and will be needed for finding maxima/minima.
