1 Closure categorization. 2  Check and confirm that the initial incident categorization was correct or, where the categorization subsequently turned out to be incorrect, update the record so that a correct closure categorization is recorded for the incident-seeking advise or guidance from the resolving group(s) as necessary.
In mathematics, the term generating function is used to describe an infinite sequence of numbers (a n) by treating them as the coefficients of a series expansion. The sum of this infinite series is the generating function.
Two characteristics of functions that you should become comfortable with are domain and range. The domain is the set of inputs (x values) for which the function is defined. Consider the following two functions: f(x) = x2 and g(x) = 1/x. In f(x), any value of x can produce a valid result since any number can be squared. In g(x), though, not every value of x can generate an output: when x = 0, g(x) is undefined.
