Unit 1: Polynomial & Rational Functions
Precalculus · Unit 1 · Paper 2

Polynomial & Rational Functions 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 37 terms and is the same for everyone, so a teacher can assign “Unit 1, Paper 2” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

The rational function f is given by f(x) = (2x² − 8)/(x² − x − 6). (a) Find all zeros of f and all values of x where f is undefined, and classify each undefined point as a hole or a vertical asymptote. (b) Determine the horizontal asymptote of the graph of f, and justify your answer using end behavior. (c) Write the coordinates of the hole in the graph of f.
