If you graph the function y = 3x  and y = 3–x  the graphs create a reflection about they-axis.  Explain why this occurs.
Now, if you graph the function y = 3x  andy = -(3x)  the graphs create a reflectionabout the x-axis instead.  Explain why, indetail,  the reflection changes from being about they-axis to being about the x-axis.
Now, know the answers to #11 and #12, if we take the basefunction y = 3x what would cause a reflection about theorigin?  Explain why this happens.
