These questions should be attempted only after you have completed all the homework assignments. You may need a calculator to solve a couple of these problems, however the exam questions will be choosen in such a way that you do not need a calculator. 1. (Section 1.6) Know the parent functions on page 70. (a) Graph the function and find the domain and range for f ( x ) = 2 - 2 x if x < - 1 4 if - 1 < x < 2 - x 2 if x 2 2. (Section 1.7) Transformations of Functions (a) Sketch the following functions by using transformations of parent functions: f ( x ) = - 3( x - 2) 3 - 4 g ( x ) = 1 2 - x - 3 h ( x ) = - 1 3 | x | - 1 (b) Using the graphs from part (a) find the domain and range. 3. (Section 1.8) Combinations of Functions (a) Let f ( x ) = x - 1 and g ( x ) = 4 - x 2 . Find following functions with their domain: ( f - g )( x ) ± f g ² ( x ) ( fg )( x ) ( f + g )( x ) (b) Find the functions f and g such that ( f g )( x ) = 1 + x 2 x 2 (c) Let f ( x ) = 3 - x and g ( x ) = 1 x 2 . Find the following functions with their domain: ( f g )( x ) ( g f )( x ) ( f f )( x ) ( g g )( x ) ( f f f )( x ) (d) If f and g are odd functions, show that the composite function
