Inverse functions

For the final lesson in the three week plan in maths we have been looking at Inverse Functions. If you missed the lesson or just didn’t get it, here is a video by a very good but very american teacher. For what is required for Core 3, you don’t need to watch any further than about 7 minutes 13 seconds.

If you find the style a bit too much and you require something a bit more sober then here are some notes.

Combined Transformations and Composite Functions

For the second week of the year twelve three week plan, here are some supporting materials on Combined Transformations and Composite Functions.

First of all a nice animation on which order to do composite functions in.

Then some extra notes on combined transformations.

Domain and Range

Following on from the year twelve lessons this week, here are some supporting materials on domain and range.

First of all, a clear and concise video explaining domain and range:

Next a link to some notes and examples on Domain and Range.

Finally a link to an activity for finding the domain and range of a function using its graph.
