Directions: For each question, choose the best answer from the four choices. For student-produced response questions on the real exam you would enter a numeric answer directly; in this practice set all questions are multiple-choice. You may use the Desmos graphing calculator at any point in the Math section. Select an answer to see whether it's correct along with a full explanation — this is a self-study feature not present in the real exam.
