2-7 Guide and Intervention (continued) Parent Functions and Transformations Transformations Transformations of a parent graph may appear in a different location, may flip over an axis, or may appear to have been stretched or compressed. Example: Describe the reflection in = Then graph the function. y –|x|. The of = is a reflection of the graph of = |x| in the y –|x| y x–axis. Exercises Describe the translation in each function. Then graph the function. |x 1. = 4 2. = + 5| 3. = 3 y x y y – – Describe the dilation in each function. Then graph the function. |x| 4. = 5x 5. = 6. = 2 y y y
