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.

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:

Now the domain is the set of all x values that if we input it into this function, we're going to get a legitimate output. We're going to get a legitimate f of x.

Functions assign a single output for each of their inputs. In this video, we see examples of various kinds of functions.

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 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".

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 a function according to the algebraic limitations of that function.

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 …

And we've already talked a little bit about the notion of a domain. A domain is the set of all of the inputs over which the function is defined. So if this the domain here, if this is the domain here, …
