Domain Finder Algebra

Enter the function you want to domain into the editor.

Domain finder algebra. To find the domain of a function that has a fraction in it set the denominator so it s equal to 0. The range is the set of possible output values which are shown on the y axis. Keep in mind that if the graph continues beyond the portion of the graph we can see the domain and range may be greater than the visible values.

We can also define special functions whose domains are more limited. So these two techniques solve the problem of knowing how to find the domain of a function algebraically. To find the domain of a function just plug the x values into the quadratic formula to get the y output.

The domain calculator allows you to take a simple or complex function and find the domain in both interval and set notation instantly. Consider a simple linear equation like the graph shown below drawn from the function y x 2 10 y x 2 10. Another way of doing so is by looking at the graph if available.

The domain of a function is the set of all possible inputs for the function. We can demonstrate the domain visually as well. For example the domain of f x x is all real numbers and the domain of g x 1 x is all real numbers except for x 0.

To find the range of a function first find the x value and y value of the vertex using the formula x b 2a. They will give you a function and ask you to find the domain and maybe the range too. Only when we get to certain types of algebraic expressions will we need to limit the domain.
