MATHEMATICS LEYEL 2 TESTFor each of the following problems, decide which is the BEST of the choices given. If the exact numerical value is notone of the choices, select the choice that best approximates this value. Then fill in the corresponding circle on theanswer she€t.Notes: (1) A scientific or graphing calculator will be necessary for answering some (but not all) of the questions inthis test. For each question you will have to decide whether or not you should use a calculator'(2) For some questions in this test you may have to decide whether your calculator should be in the radianmode or the degtee mode.(3) Figurei that accompany problems in this test are intended to provide information usefirl in solving theproblems. They are drawn as accurately as possible EXCEPI when it is stated in a specific problem that its figure is notdrawn to scale. A11figures lie in a plane unless otherwise indicated.(4) Unless otherwise specified, the domain of any function / is assumed to be the set of all real numbers rrbr which /(x) is a real number. The range of / is assumed to be the set of all real numbers /(.r), where .r is inthe domain of I(5) Reference infonnation that may be useful in answering the questions in this test can be found on thepage preceding Question 1' LISE THI. spACE FoR '.RATCH woRK.I=I.
