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.

How to find domain and range from a graph (video) | Khan Academy
The domain of a function is the set of values that we are allowed to plug into our function. So if you are going to check for the domain, usually find for the following 3 points:
Examples finding the domain of functions - Khan Academy
If you wanted to keep x minus two from being zero, x just can't be equal to two, and so typically, people would say that the domain here is all real values of x such that x does not equal two.
Rational functions (video) - Khan Academy
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 …
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.
Determine the domain of functions (practice) | Khan Academy
Determine the domain of a function according to the algebraic limitations of that function.
Intro to rational expressions (article) | Khan Academy
The domain of any expression is the set of all possible input values. In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 …
Sequences and domain (video) | Sequences | Khan Academy
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 …
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".
