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 long as it isn’t 0.

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 by connecting …

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 (output) it …
