Chapter 2.4, Problem 47E

Exercises 47-49 will help you prepare for the material covered in the next section. In each exercise, graph the functions in parts (a) and (b) in the same rectangular coordinate system.

a. Graph f ( x ) = | x | using the ordered pairs ( − 3 ,   f ( − 3 ) ) , ( − 2 ,   f ( − 2 ) ) ,   ( − 1 ,   f ( − 1 ) ) ,   ( 0 , f ( 0 ) ) ,   ( 1 , f ( 1 ) ) ,   ( 2 , f ( 2 ) ) , and ( 3 , f ( 3 ) ) .

b. Subtract 4 from each y-coordinate of the ordered pairs in part (a). Then graph the ordered pairs and connect them with two linear pieces.

c. Describe the relationship between the graph in part (b) and the graph in part (a).
