I get mixed up when graphing derivatives. If I'm given the graph of f how do I get f' and f"?
Answered by Steve
in general, you cannot. You can, however, tell where f' is positive or negative or zero, or where f" is positive or negative or zero.

Okay, what are the rules for determining positive, negative, or zero?
Answered by Steve
oh, come on.

f' is the slope of f. So, if f' > 0, f is increasing.

f" indicates concavity. If f" > 0, the graph of f is concave up.
