In plain English, this definition means: The domain is the set of all possible x-values which will make the function 'work', and will output real y-values. If a rule describes a relation, it should also specify the domain. The domain of a function is the complete set of possible values of the independent variable. The domain and range of a relation are often described using set notation. The range is the set of outputs that the system or function will produce when given the. This set is the values that the function shoots out after we plug an x value in.

We will look at the definition of a function, the domain and range of a function, and what we mean by.

The range of a function is the set of values that the function assumes. In these notes we will cover various aspects of functions. This set is the x values in a function such as f(x). The range of a relation is the set of values of $y$ in the relation. Put simply, the domain represents the inputs to a system or a function. Domain and Range The domain of a function is the set of values that we are allowed to plug into our function. The domain of a relation is the set of values of $x$ in the relation.

The set of all first elements of a set of ordered pairs is known as the domain, and the set of all second elements of a set of ordered pairs is known as the range.Īlternatively, the domain is the set of independent values, and the range is the set of dependent values.
