### KS Comments:

##### For the transformations in (i)

There is a lot of different answers thats possible. I just did one, feel free to comment alternative methods.

The graphs here is hard, I did suggest that piecewise function will come out previously but didn’t expect it to be so tricky. The graphs is manageable, but the second graphs is bit more tricky here, as students need to scale out the domain too.
