<p>In this lesson, you will learn to identify the inputs and outputs as the domain and range of a function. You will calculate real-world examples using money, area, and perimeter to understand how the use of the domain and range of a function can be applied in everyday life.</p>
<p>When you finish this lesson, you will be able to:</p>
<ul>
  <li> Describe the &ldquo;domain&rdquo; and &ldquo;range&rdquo; of a function. </li>
  <li> Determine a reasonable domain and range for the function when given a description of a function in a situation. </li>
</ul>
<p>Here are the <strong>activities</strong> that will help you reach those goals:</p>
