Definition of function in general mathematics
WebThere are also rules for building sets that allow you to give recursive definitions of functions. So, the 'standard' ways of constructing functions are justified by axiomatic set theory. It should be noted though that no model of set theory is known, and that if one is ever found it will immediately imply that the theory is inconsistent. WebFunctions may be represented by mathematical equations as follows: a) y = 2x − 1 , b) y = x2 + 1 , c) y = 1 x. All the above equations represent y as function of x because for each for each value of x in the domain, we obtain exactly one value of y. x is called the independent variable and y is the dependent variable.
