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.

What are rational functions? How do we plot them? What is their domain and range? Let's find out. We break down the definition of the function given in set-builder form and plot the graph …

Actually, on a Cartesian plane, we only use the domain and range of real numbers (not rational numbers), so we do not include imaginary numbers. These are not on our normal Cartesian (x …

The domain is the possible numbers that the function will work for. Sometimes it is limited. For the function f (x) = 1/x, you cannot divide by zero, so the range would be all real numbers except …

Learn how to determine the domain and range of a function from its graph with this concise tutorial on Khan Academy.

The domain of a function, you'll often hear it combined with domain and range. But the domain of a function is just what values can I put into a function and get a valid output.

Let's take a look at an example where plotting a graph can help us figure out the domain and range of a function. Even if that function is not a polynomial. We break down the definition of …
