A collection of resources on Transformations of Functions this week. The subject content for GCSE content includes: 13.sketch translations and reflections of a given function and for A Level we have:

From Transum, this wonderful resource, **Transformations of Functions** shows how various transformations affect the graph of a function. There are 16 possible transformations to try including examples of combinations of transformations. Having chosen your transformation you can try sketching the transformed function before revealing the answer.

Remember that Transum’s index is very helpful, if we look at the **Graphs menu**, we see numerous activities on graphs, also, on the left hand side activities mapped to a curriculum for graphs.

For some helpful notes, check **Mathisfun!**. Scroll to the bottom of the page for some **multiple choice questions** to try. The examples include combinations of transformations.

A very helpful feature of the questions on Mathisfun is the very clear feedback, here for example, we see:

It is very helpful indeed when studying this topic to use graphing software to experiment and try out different functions. Note how easy it is using the Desmos graphing calculator to show a graph and then the same graph after a transformation. For example see **here** the graph of x^{2} and (x+a)^{2 }(or click on the image).See these Desmos pages – **Transformations** and **Transformations – Advanced**.

This is a lovely resource on GeoGebra, **Transformation of Graphs** from Steven Fan can be used to explore combinations of transformations.

Looking at MEI’s student tasks, several are available for exploring transformations with instructions for using the software and questions to explore. Tasks are available for Autograph, Casio, Desmos and GeoGebra.

Further helpful resources:

On Dr Frost, **GCSE Graph Transformations** and for A Level, **Graphs and Transformations**.for Year 1 and **Functions and Graphs** for Year 2.

Owen (**Owen134866** on TES) has a library of Mathematics Further Mathematics teaching resources, these are really clearly structured with step by step examples. Graphs and Transformations can be found on TES in his **A Level Pure Mathematics Year 1/AS Collection** and Functions and Graphs which includes combinations of function can be found on TES in his **A Level Pure Mathematics Year 2 Collection**.

On **ck12, 1.7 Function Graphs: Combined Transformations**, there are several very useful examples of combining transformations. This content is very clear.

**Maths Genie** – Transforming Graphs GCSE **questions** and **solutions**. Sketching and Transforming Curves A Level **questions** and **solutions**.

Corbett Maths **Transformations of Graphs** practice questions.

On Exam Solutions, we have **worked exam questions** and helpful **video tutorials** on **Translations of Graphs**, **reflections** and **stretches**.

Notes from Mathisfun have been mentioned above, further notes include from **MathsBitsNotebook.com**, this on **Transformations of Functions**. and the **A Level** course material from CIMT includes **Graph Transforms**.
