### Lesson Focus

#### The Domain and Range of a Function

Algebra-1

You will identify the domain (input) and range (output) of a discrete function, and write the domain and the range of a continues function using an inequality or interval notation.

### Now You Know

After completing this tutorial, you will be able to complete the following:

• Determine the domain and range of a discrete function given by an equation, graph, table, or verbal rule.
• Write the domain and range of a function using an inequality or interval notation.

### Everything You'll Have Covered

Domain and range terminology explained

The domain, often referred to as the input, is the set of all the possible x values for a given function. The range, often referred to as the output, is the set of all the possible y values for that same function. ### Tutorial Details
