Domain And Range Number Line

The domain of a function is the set of all possible input values while the range is the set of all possible output values.

Domain and range number line. For many functions the domain and range can be determined from a graph. Domain and range tips for entering queries. The line and function to the left has a domain and range of all real numbers because as the arrows indicate the graph goes on forever both negatively and positively.

Wolfram alpha is a great tool for finding the domain and range of a function. A graph of a typical line such as the one shown below. Learn what the domain and range mean and how to determine the domain and range of a given function.

The same applies to the vertical extent of the graph so the domain and range include all real numbers. For the cubic function latex f left x right x 3 latex the domain is all real numbers because the horizontal extent of the graph is the whole real number line. It also shows plots of the function and illustrates the domain and range on a number line to enhance your mathematical intuition.

Linear function is almost always going to be all real numbers. Enter your queries using plain english.
