5.9 Connecting a Function, Its First Derivative, and Its Second Derivative
In short
In this topic, the superficial details of contextual applications are stripped away to focus on abstract structures and formal conclusions. You must relate the key features of the graphs of a function (f), its first derivative (f'), and its second derivative (f").

What else do you need to know about Connecting a Function, Its First Derivative, and Its Second Derivative?
This involves using calculators to graph functions and their derivatives to explore related features and confirm analytical results. You should practice matching graphs of functions to their derivatives and explaining your reasoning to prevent misconceptions where they might conflate the characteristics of a derivative's graph with those of the original function.
How is Connecting a Function, Its First Derivative, and Its Second Derivative tested on the exam?
On the AP Exam, sound reasoning must be accompanied by clear communication. You must avoid nonspecific language (e.g., using 'it' or 'the function') and explicitly refer to f, f', and f" by name. A common pitfall is misinterpreting the characteristics of a derivative's graph as those of the original function, or relying on insufficient descriptions like 'the graph of f is increasing because it's going up'. Arguments about f should be based directly on the graph of the derivative (e.g., 'f is concave up on a < x < b because the graph of f' is increasing on a < x < b').
