Thus, here is an example of a function: [{1, 1}, {2, 1}, {3, 2}] This function consists of three pairs, whose first members are 1, 2 and 3. It is customary to give functions names, like f, g or h, and if we call this function f, we generally use the following notation to describe it: f(1) = 1, f(2) = 1, f(3) = 2. The first members of the pairs are called arguments and the whole set of them is called the domain of the function. Thus the arguments of f here are 1, 2 and 3, and the set consisting of these three numbers is its domain.
Road speed limits are used in most countries to set the maximum (or minimum in some cases) speed at which road vehicles may legally travel on particular stretches of road. Speed limits may be variable and in some places speeds are unlimited (e.g. on some Autobahn sections in Germany).
Under pressure from the U.S., the province lowered the limit to 100 km/h in 1976. And thatâs where it remains today, even though most other jurisdictions have since raised theirs. Most U.S. states have a 70 mph (113 km/h) limit. The highest speed limit in North America is 85 mph (140 km/h) on Texasâs State Highway 130. Ontarioâs low limit is often defended on the basis of speed elasticity â the assumption that drivers will automatically exceed the posted limit by a certain margin.
