## Is the domain the independent or dependent variable?

independent variable The domain variable (x) is referred to as the independent variable. The range variable (y) is referred to as the dependent variable. Usually function notation is used to represent a relation which is a function. Given that relation "f" is a function, it can be represented as y = f(x) (stated as "y equals f at x").

## What are the domain rules?

What are the Rules to Find the Domain of a Function?

• f(x) = polynomial, the domain is the set of all real numbers.
• f(x) = 1/x, domain if the set of all real numbers but x≠0.
• f(x) = √x, domain if the set of all real numbers such that x ≥ 0.
• f(x) = ln x, domain is the set of all real numbers such that x > 0.

## What is domain and range in function?

Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Overall, the steps for algebraically finding the range of a function are:

1. Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2. Find the domain of g(y), and this will be the range of f(x). …
3. If you can't seem to solve for x, then try graphing the function to find the range.

## How do you write the domain?
