SL Core 2.2
The domain and range of functions are commonly intervals of real numbers.
For example, if f(x) is defined for −1<x≤5, we can write the domain
(∈ means "in" or "element of", and R is all real numbers)
We can also use the equivalent interval notation
where ( means that end is not inclusive (−1<x) and ] means that end is inclusive (x≤5).
These can also be visualized on a number line:
