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).
Most speed limits are set by state or local statute, although each state allows various sub div isions to set a different, generally lower, limit. The highest speed limits are generally 75â80 mph (120â130 km/h) in western states and 70 mph (115 km/h) in eastern states.A few states, mainly in the Northeast Megalopolis, have 65 mph (105 km/h) limits, and Hawaii has a maximum limit of 60 mph (95 km/h).Portions of the Idaho, Montana, Nevada, South Dakota, Texas, Utah, and Wyoming road networks have 80 mph (130 km/h) limits.ost speed limits are set by state or local statute, although each state allows various sub div isions to set a different, generally lower, limit.
