Click on the link below for practice problems on transformations.
If you scroll down, you will see the answers to each problem. Keep in mind for the “Name, describe and give the function” problems, the answer key is incomplete. A complete answer is something like: (x,y)->(-x,-y), a 180 rotation about the origin.
Below is a review of the functions for reflections and rotations on the coordinate plane.
There are also older posts going over how to do reflections and compositions of transformations.
