Test on Friday

I'm confused over which subjects we're going over- it seems like a mix of past topics. Can you tell us which chapters we should be paying more attention on? Because I'm looking up the topic that's stated on our hw, and the chapter index doesn't give many pages on it...

When they say "justify our answer," I'm stumped because when the hw answers justifies it, it's often in different ways. Is there one, consistent, formula for justifying your answer? Like:

The realtive max is at x=1 because f '(x) changes from postive to negative at tis value
The relative max is at x=1 because f (x) changes from decreasing to increasing at this value

Just making sure.

Logistic and exponential growth as well as first and second derivative tests (which is pretty broad, I admit) for Friday's Quiz.
Did you not receive a copy put out by the College Board that explains the Role of Sign Charts as well as what "Justify your answer" means? No, there is no specific one-answer fits them all in this case. Why? Each question is unique, so there's no simple answer, sorry.
