A rule will accept almost any number you hand it.
The situation it models will not.
One graph, and two questions we do not have names for yet.

0 ≤ t ≤ 35
every input the graph reaches
— the domain
10 ≤ h ≤ 75
every output it produces
— the range
The rule says what is possible.
The situation says what is
allowed
