## Reflection: Intervention and Extension Finding the Inverse of a Function Day 1 of 2 - Section 3: Finding Inverses using tables and graphs

Students sometimes need a refresher about what is meant by reflecting across the y=x line. To help students I print off these graphs. I give each student the graphs. Students label each graph and identify points on the function and its' inverse. This allows students to see how the points have changed. I then have the students fold the graph along the y=x line to see how the graphs overlap.

This is a quick reteaching tool that connects for some of the students.
