Sharks, grizzly bears and big cats may strike fear into your heart and limbic brain, but they do not even come close to being the deadliest animals on earth. Of the top ten deadliest creatures to humans most are smaller than a silver dollar! One of the few with scary fangs will likely surprise you.
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=xÂ² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
In mathematics, and more specifically in naive set theory, the domain of definition (or simply the domain) of a function is the set of input or argument values for which the function is defined. That is, the function provides an output or value for each member of the domain.ormal definition [edit]. Given a function f: X â Y, the set X is the domain of f; the set Y is the codomain of f. In the expression f (x), x is the argument and f (x) is the value.
