Domain And Range
The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y.
Domain and range. What is domain and range. 2 3 4 6 range. The domain of a function is the set of all possible input values while the range is the set of all possible output values.
So the domain of the function is. The domain and range of a function is all the possible values of the independent variable x for which y is defined. In its simplest form the domain is all the values that go into a function and the range is all the values that come out.
The domain is the set of all possible x values which will make the function work and will output real y values. As a function table and as a set of coordinates. Before getting into the topic of domain and range let s briefly describe what a function is.
The example below shows two different ways that a function can be represented. And i can take any real number square it multiply it by 3 then add 6 times that real number and then subtract 2 from it. What is a set of all of the valid inputs or all of the valid x values for this function.
In mathematics a function can be compared to a machine that generates some output in correlation to a given input. The domain of a function is most commonly defined as the set of values for which a function is defined. For example a function that is defined for real values in has domain and is sometimes said to be a function over the reals the set of values to which is sent by the function is called the range.
The range of a function is all the possible values of the dependent variable y. The domain is all the x values and the range is all the y values. To give the domain and the range i just list the values without duplication.
