35 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.
Separate direction from concavity. A function can be increasing while concave down. Decide whether it's rising or falling first, then whether that change is speeding up or slowing down.
Read the algebra, then predict the graph. Factors give zeros, the leading term gives end behavior, and the denominator gives asymptotes and holes. Most Unit 1 questions reward this habit.
Watch the "not" and the direction of transformations. Inside changes act opposite to their sign: f(x − 3) shifts right. Small wording differences change the answer.
Read the explanations even when you got it right. Each one reinforces a rule that tends to reappear on the exam in a slightly different form.
