Determine The Domain Of Each Function

Informally if a function is defined on some set then we call that set the domain.

Determine the domain of each function. The range is the set of possible output values which are shown on the y axis. We can also define special functions whose domains are more limited. The values taken by the function are collectively referred to as the range.

When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points. Free functions domain calculator find functions domain step by step. Yet there is one algebraic technique that will always be used.

Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x x axis. These won t be terribly useful or interesting functions and relations but your text wants you to get the idea of what the domain and range of a function are.
