We can also define special functions whose domains are more limited.

How to write the domain of a function. The domain of a function is the set of all possible inputs for the function. Write the domain in interval form making sure to exclude any restricted values from the domain. A codomain can contain every possible output not just those that actually appear. F x x 2 2. The format for expressing the domain is an open bracket parenthesis followed by the 2 endpoints of the domain separated by a comma followed by a closed bracket parenthesis.

Is defined for all real values of x because there are no restrictions on the value of x. The set x is the domain of g left x right in this case whereas the set y 1 0 1 8 is the range of the function corresponding to this domain. If we apply the function g on set x we have the following picture. Here are a few things you need to know about writing the domain of a function. The codomain is similar to a range with one big difference.

Since x 2 is never negative x 2 2 is never less than 2 hence the range of f x is all real numbers f x 2. For example the domain of f x x is all real numbers and the domain of g x 1 x is all real numbers except for x 0. The range is the set of y values that are output for the domain. Writing the domain of a function involves the use of both brackets and parentheses. This means that the domain goes from 1 to 5.

The domain is the set of x values that can be put into a function in other words it s the set of all possible values of the independent variable. F is defined on x. When a function f has a domain as a set x we state this fact as follows. Hence the domain of f x is all real values of x.
