MATHEMATICS LEVEL 2

For each of the following problems, decide which is the BEST of the

choices given. If the exact numerical value is not one of the choices, select

the choice that best approximates this value. Then fill in the

corresponding oval on the answer sheet.

Notes: (1) A scientific or graphing calculator will be necessary for

answering some (but not all) of the questions on this 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 radian mode or the degree mode.

(3) Figures that accompany problems on this test are intended to

provide information useful in solving the problems. They are drawn as

accurately as possible EXCEPT when it is stated in a specific problem that

its figure is not drawn to scale. All figures lie in a plane unless otherwise

indicated.

(4) Unless otherwise specified, the domain of any function f is assumed

to be the set of all real numbers x for which f(x) is a real number. The

range of f is assumed to be the set of all real numbers f(x), where x is in

the domain of f.

(5) Reference information that may be useful in answering the

questions on this test can be found below.
