1.2 Review Worksheet (continued)
1.2.4 Introduction to Parent Functions Identify the parent function for g from its function rule. Then graph g on your calculator and describe what transformation of the parent function it represents. 32. g ( x ) = x 2 − 1 33. = − g x x ( ) 2 34. g ( x ) = x 3 + 3
Graph the data from the table. Describe the parent function and the transformation that best approximates the data set. 35. 36.
