Integrated Math 2 | Final Exam Outline Review Name:_______________________ Date:______________________ Instructions: With finals in the near future, this review outline will help support and prepare you for the Integrated Math 2 mock final and the final examination for semester 1. During the course of Semester 1, we have covered the following topics: Probability Quadratics Functions Structure of Expressions Quadratics Equations You have learned a tremendous amount of information, and not all topics will be covered. This outline is here to guide you on what you need to do in order to pass the examinations when you return from break. Word of wisdom: attempt to solve every problem. If you cannot do one, at least you have tried. It is better to have tried than to not have tried. Word of wisdom #2: questions on this review might reappear on your exam.
