DIRECTIONS FOR MULTIPLE CHOICE QUESTIONS: For this section, you may use the available space for your scratchwork. Solve each problem, and fill in the corresponding oval for your answer on the answer sheet. DIRECTIONS FOR GRID-IN QUESTIONS: These questions require you to solve the problems on your own and enter your answers into the corresponding grids by marking the appropriate ovals. Do not mark more than one oval per column. Columns not needed should be left blank. You will receive credit only if you fill the ovals in correctly. Some questions may have more than one correct answer. Only grid in one of the correct answers. No answer will have a negative value. Mixed numbers, such as 1 1 must be entered as 1.5 or 3/2. 2 Decimal answers with more digits than the grid can accommodate can be either rounded or truncated, but you must fill the entire grid. For example, 0.666... can be entered as 2/3,.666 or.667. If.66 or.67 is entered instead, it will be scored as incorrect. Notes 1. You are allowed to use a calculator on this section. 2. Only real numbers are used. 3. Figures that accompany problems in this section are provided to help you solve the problem. You can assume that figures are accurately drawn to scale EXCEPT when it is noted otherwise. All figures lie in a plane unless otherwise noted. 4. The domain of any function f is defined as the set of all real number x values for which f(x) is a real number, unless otherwise noted.
