# How to find domain of an equation

Step 1: Write down the function in the form \\) Step 2: Solve it for \ to write it in the form, \\) Step 3: The domain of the function \\) is the range of \\). Example: For the function

## Finding the Domain Without the Graph

Determine the domain and range of the function f of x is equal to 3x squared plus 6x minus 2. So, the domain of the function is: what is a set of all of the valid inputs, or all of the valid x values for this function? And, I can take any real
From Graph

Finding the domain requires determining the values of the independent variables (which is usually x) that have been allowed to use. At the bottom of the fraction, 0 is usually debarred or we

## 3.3: Domain and Range

To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation. A function with a variable inside a radical sign. To find the domain of this type of function, just set the terms inside the radical sign to >0 and solve to find the values that would work for x. See more

## Write Domain and Range Given an Equation

Functions assign outputs to inputs. 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. We can also define special functions whose
