Several factors can be responsible, including: 1  Heredity: If your dad had oily hair, chances are you will, too. 2  Hormonal fluctuations: In adult women, it may come with the menstrual cycle or using birth control pills. 3  Bulking up: Excessive oil is a side effect of using androgenic hormones to increase body mass.
At first glance, a function looks just like a relation. 1  It's a set of ordered pairs such as { (0,1) , (5, 22), (11,9) }. 2  Like a relation, a function has a domain and range made up of the x and y values of ordered pairs.
Functions are named blocks of code that carry out specific tasks and can be reused in your program. There are two types of functions in ActionScript 3: methods and function closures. The context in which the function is defined determines whether a function is a called a method or a function. A function is called a method if you define it as part of a class definition or attach it to an instance of an object.
