Transformation of Functions
This interactive resource, produced by the University of Leicester, is designed to enable students to explore transformations of functions including translations, stretches, reflection in the axes and rotations.
The first activity uses function notation to explore translations parallel to the x axis and translations parallel to the y axis. The next slide contains a summary of what should be found.
The second activity investigates stretches from the y axis parallel to the x axis and stretches from the x axis parallel to the y axis. Again the relation between the transformation, the graphical representation and the function notation is seen.
There follows two further activities. The first activity explores reflections in the two axes. The second activity investigates rotations about the origin.
