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. …

Functions assign outputs to inputs. 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 …

The domain is the possible numbers n can be that would accurately describe the sequence. For example, the difference between whether n>=1 or n>=0 depends on whether the range …

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. So let's start with …

Determine the domain of a function according to the algebraic limitations of that function.

If the magnitude of x is less than 6 then x is greater than negative 6 and less than positive 6. So if we wanted to write the domain in kinda fancy domain-set notation, we could write the domain …

I'll try explain this as best as i can. Describing something as a function is sort of labelling it. Equations show the equality of two expressions. Functions are more specific than equations; …

Sal shows how to algebraically find the domain of a few different functions. Skip to main content If you're seeing this message, it means we're having trouble loading external resources on our …

Sal shows how to test whether or not a value is or isn't in the domain of a function.

Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two …
