The first test in this book is mostly new, with some problems borrowed from earlier editions, and the second test in the book is unchanged from earlier editions. I appreciate PR updating their books, but not when changes introduce errors. This is what I found so far:
Problem 10: The solution in the book uses substitution to solve this whereas I attempted to solve it using algebra. I think PR got lucky here with their substitution value because their answer choice is not correct in general.
Problem 15: There is a typo in the answer key. The correct answer is (D).
Problem 20: There is a mistake in the question. If the question reads "which of the following must be false" then the answer choice is (E). Unfortunately the question reads "which of the following must be true."
Problem 32: There is a typo in answer choice (A). It should be f(-1) not f(1). The typo results in two correct answer choices.
