Wolfram|Alpha is a great tool for finding the domain and range of a function. It also shows plots of the function and illustrates the domain and range on a number line to enhance your mathematical intuition. Learn more about: Domain and range. Tips for entering queries. Enter your queries using plain English.
The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited. Questions. Tips & Thanks. Want to join the conversation? Log in. Sort by: Top Voted
Domain is all the values of X on the graph. So, you need to look how far to the left and right the graph will go. There can be very large values for X to the right.
