For this case we have the following vertices: D = (- 1, -1) E = (1, -1) F = (- 1, -6) Then, the vertices after the transformation are: D '= (- 1, 1) E '= (1,1) F '= (- 1,6) The x coordinate remains the same The y coordinate change sign. Therefore, the transformation is: Reflection on the x axis. Answer: Reflection on the x axis. option 1
