Function dftusefft
Webfunction, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in … WebA function may be thought of as a rule which takes each member x of a set and assigns, or maps it to the same value y known at its image. x → Function → y A letter such as f, g or h is often used to stand for a function. The Function which squares a number and adds on a 3, can be written as f (x) = x2+ 5.
