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).
Footspeed, or sprint speed, is the maximum speed at which a human can run.It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports, such as association football, rugby, American football, track and field, and basketball.he fastest human footspeed on record is 44.7 km/h (12.4 m/s or 27.78 mph), seen during a 100 meters sprint (average speed between the 60th and the 80th meter) by Usain Bolt. Maximum human sprint speed is strikingly slower than that of many animals.
