Unit 5: Analytical Applications
Calculus AB · Unit 5 · Paper 1

Analytical Applications unit test

A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Each paper is built from this unit’s 17 terms and is the same for everyone, so a teacher can assign “Unit 5, Paper 1” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

Let f(x) = x³ − 6x² + 9x + 2.

Find all critical points of f and classify each as a local maximum or local minimum. Justify your answer.

Find the inflection point of f and the interval on which f is concave up.

Find the absolute maximum and absolute minimum values of f on the closed interval [0, 4].
