NO CALCULATOR IS ALLOWED FOR THIS QUESTION. Show all of your work. even though the question may not explicitly remind you to do so. Clearly label any functions. graphs. tables. or other objects that you use. Justications require that you give mathematical reasons. and that you verify the needed conditions under which relevant theorems, properties. det'mitions. or tests are applied. Your work will be scored on the correctness and completeness of your methods as well as your answers. Answers without supporting work will usually not receive credit. Unless otherwise specied. answers (111nneric or algebraic) need not be simplied. If your answer is given as a decimal approximation. it should be correct to three places after the decimal point. Unless otherwise specied. the domain of a function f is assumed to be the set of all real numbers a: for which f (3:) is a real number. 17 3 mi cos for0
