Document Summary
The notation some input from means maps from into. In other words, the function transforms into an output which is in the set. 2. 2 definition: function, domain, range is a rule which takes every element which is part of and assigns it one. A function and only one element which is part of. Let(cid:495)s define the input from as the function applied to that element in. )t(cid:495)s just there for convenience. so that both the inputs and outputs are. Usually, you(cid:495)ll be dealing with functions are the domain of the real. This is where the rule being applied to each input differs across the domain. For example, take the absolute value definition above: Also, note how we used open brackets above for. The domain is clearly on which part of the domain is being input. , and it(cid:495)s a legitimate function, but the rule changes depending.
