1)Finitely many lines divide a plane into regions. Show these regions can be coloured by two colours in such a way that neighboring regions have different colours. 2)Showthat there are $2^n%$ number ...

### What should I call the "important" values of x?

For function transformations I use "base point" ($y=a^x$ has base point $(0,1)$, $y = \frac{1}{x}$ has base point $(0,0)$, even though it isn't on the graph). In calculus I use "point ...
