A function is a rule that for every input assigns a specific output.

But in fact they are very important in defining a function.
The output usually y is called the dependent variable. The domain and range of a function is all the possible values of the independent variable x for which y is defined. Then the domain is where the function lies horizontally and the range is where the function lies vertically.
If we draw a graph with the x coordinate as the horizontal values and y coordinate as the vertical values. The domain is the set of all input values. As a function table and as a set of coordinates.
The domain of a function is the set of all possible input values while the range is the set of all possible output values. 5th grade math 6th grade math pre algebra algebra 1 geometry algebra 2 college students are given relations in the form of sets of ordered pairs and graphs and are asked to find the domain and range of the given relations and determine if the given relations represent functions. The set of all possible inputs is called the domain.
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. Definition of a function domain and range. The domain is the set of all possible x values.
The range is the set of all output values. The example below shows two different ways that a function can be represented.
