Mathematics Advanced Year 11 - Module 1 - Lesson 12
Combined Transformations
1. Key Ideas
In a video game, every character on screen is just a basic image that has been stretched, flipped, rotated, and moved into position. Game developers do not redraw the character for every frame — they apply combined transformations. In this lesson, you will learn to do the same thing with functions: stack multiple transformations together and read the result like a pro.
- How to combine translations, reflections, and dilations in one equation
- Why the order of reading transformations matters
2. Success Criteria
By the end, you should be able to:
- How to combine translations, reflections, and dilations in one equation
- The standard form $y = af(b(x - h)) + k$
- How each parameter affects the graph

5. Short Answer Questions
1. Explain this lesson goal in your own words: "How to combine translations, reflections, and dilations in one equation". Use one specific example from the lesson.
2. Apply this idea to a new example: "The standard form $y = af(b(x - h)) + k$". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Combined Transformations: "How each parameter affects the graph".
6. Extend: Apply the Idea
A student gives a memorised answer about Combined Transformations but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
