AP Calculus BC · Unit 5: Analytical Applications of Differentiation
5.8 Sketching Graphs of Functions and Their Derivatives
In short
You are expected to identify how mathematical characteristics or properties of functions are related across graphical, numerical, and analytical representations. You must be able to match graphs of functions to their derivatives and explain their reasoning. The focus is on abstract structures and formal conclusions, stripping away superficial details of contextual applications.

What else do you need to know about Sketching Graphs of Functions and Their Derivatives?
You must avoid misinterpreting the characteristics of the graph of a derivative as though they are characteristics of the original function.
How is Sketching Graphs of Functions and Their Derivatives tested on the exam?
On the AP Exam, sound reasoning must be accompanied by clear communication. You often lose marks by using nonspecific language that conflates different functions (e.g., using 'it' or 'the function' rather than explicitly naming f, f', or f''). When justifying conclusions based on a derivative graph, you should make arguments directly based on that graph (e.g., 'f is concave up on a < x < b because the graph of f\' is increasing on a < x < b'). Relying on insufficient evidence or informal descriptions, such as stating 'the graph of f is increasing because it\'s going up', is penalized.
