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.
What kind of functions don't have a domain of all real numbers? Well, if the domain is the set of all real numbers for which the function is defined, then logically we're looking for a function that has certain input values that do not produce a valid output, i.e., the function is undefined for that input.Here is an example: This function is defined for almost any real x.hat kind of functions don't have a domain of all real numbers? Well, if the domain is the set of all real numbers for which the function is defined, then logically we're looking for a function that has certain input values that do not produce a valid output, i.e., the function is undefined for that input.
