- 1 - Math 111 Review Exercises for the Final Exam The following are review exercises for the Math 111 final exam. These exercises are provided for you to practice or test yourself for readiness for the final exam. There are many more problems appearing here than would be on the final. These exercises represent many of the types of problems you would be expected to solve on the final, but are not meant to represent all possible types of problems that could appear on the final exam. Your final exam will be in two parts: the first part does not allow the use of a calculator, and the second part does allow the use of a graphing calculator. Since the exercises in this review sheet are mixed together, we have put a symbol next to exercises or parts of exercises where you WILL be allowed to use the graphing calculator: otherwise you should be able to solve the problem WITHOUT a calculator. Such a symbol will not be on the final exam. Please note that for the final, you may use any graphing calculator except the TI-89, TI-Inspire, and any calculator with a QWERTY keypad. Show all your work: unsupported results may not receive credit. 1.
