How to find the domain of a function (video) | Khan Academy
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.
Worked example: domain of algebraic functions - Khan Academy
The domain needs to be restricted to avoid any input (X-value) that would cause the denominator to be = 0. We do this by looking at each factor in the denominator and finding the value that would make …

Domain of advanced functions (video) | 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.
Worked example: determining domain word problem (real numbers)
The domain of a function, that's a set of all the inputs for which the function is defined. And the inputs here, this is t and it represents days and if I input t, the number of days, into the function h, it'll output …

Intro to composing functions (video) | Khan Academy
I'll just summarize this whole lesson in a simple way so it's easier to understand. (Intro): In basic Algebra we have an equation with an x and a y. Functions are the equations to get an input (x) to an output …
Determining whether values are in domain of function
The domain is the set of values that get "plugged into" the function (the inputs) while the range is the set of values that the function assumes/produces after "going through the function".
