## How do you find the domain and range of a function?

To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

**How do you find domain in Algebra 2?**

To find the domain, find all areas of the number line where the fraction is defined. because the denominator of a fraction must be nonzero. Factor by finding two numbers that sum to -2 and multiply to 1. These numbers are -1 and -1.

### What is range and domain in algebra?

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.

**What is the range in Algebra 2?**

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.

## How do you find the range in Algebra 2?

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

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

### What is domain and range in algebra?

Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
