Domain And Range List
The above list of points being a relationship between certain x s and certain y s is a relation.
Domain and range list. For many functions the domain and range can be determined from a graph. A piecewise function is described by more than one formula. Before getting into the topic of domain and range let s briefly describe what a function is.
A piecewise function can be graphed using each algebraic formula on its assigned subdomain. 2 3 4 6 range. The domain is all the x values and the range is all the y values.
In this article we will learn what a domain and range of a function mean and how to calculate the two quantities. The example below shows two different ways that a function can be represented. The range of a function is all the possible values of the dependent variable y.
3 1 3 6. As a function table and as a set of coordinates. The domain and range of a function is all the possible values of the independent variable x for which y is defined.
