22. Generalize the transformations rules from the above activity. These rules should work for any parent function and transformation.

Extension:

In the previous activity, many different graphs were presented. Each graph, however, had only one transformation. Below you are given some graphs that are the result of multiple transformations to the parent function previously presented. Using the knowledge you obtained above, generate the equation that would result in the graphs below. Use your calculator to test your equations.

1. Look at the graph below. Generate the equation that goes with the graph. Use your graphing calculator to test you equation. Also, describe the transformations that took place.

2. Look at the graph below. Generate the equation that goes with the graph. Use your graphing calculator to test you equation. Also, describe the transformations that took place.
