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:

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.

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.

When the denominator is 0, you are dividing by 0. Division by 0 is undefined, so any values that cause that are not included in the domain. Otherwise, you can divide by any other number as …

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 …
