Changes to the AP Precalculus workbooks

Workbooks affected were shipped BEFORE May 1, 2026.

The following list are changes we have made to our AP Precalculus lesson packets. The electronic PDF’s on our website will have these changes, but the printed workbooks shipped before May 1, 2026 will not have these changes.

1.3 Test Prep - #16.  We took out the statement about g(x) being a quadratic function. This is incorrect, because of the rate of change of g(x) = 2, then g(x) would have to be a straight line with a slope of 2.

1.8 Video, notes, practice problems - added a sign table for rational inequalities

1.10 Video, notes, practice problems - added y-value of holes

1.14 Video, notes, practice problems - changed regression problems to fit the exam format

Unit 1B review - Added problems to be adjusted from the changes to packets 1.8. 1.10, and 1.14.
