Translations, reflections and stretches are familiar ideas, but combining them in the right order can be surprisingly tricky. The standard horizontal and vertical transformations, how they move individual points, and how to apply them step by step: translations, reflections in the axes, stretches, the image of a point under combined transformations, and why the order matters. Then four questions on quadratic, exponential and cubic graphs, finishing with one linking the order of transformations to periodicity.
