I cannot understand the question. What does "Call the function" mean?

Totally lost on this question, what it want's me to do. Reviewed the video several times, and tried everything I can think of.

script.js 
function random_age(age) {
  Math.floor(Math.random() * age);
}
random_age();
index.html 
<!DOCTYPE html>

    <link href="normalize.css" rel="stylesheet">

  <body>
    <h1 class="logo"><img src="img/mash-logo.svg" /></h1>
    <p class="instructions">Fill in the blanks and your future will be foretold.</p>
    <form action="" method="post" id="mash">
      <div class="choice-bucket">
        <h4 class="highlight">What's your future pet?</h4>
        <input name="pet[]">
        <input name="pet[]">
        <input name="pet[]">
        <input name="pet[]">
      </div>
      <input type="submit" value="Tell my fortune">
    </form>

    <script src="script.js"></script>

  </body>
</html>

Call the function == Use the function

It is expressed as call the function because we need to call its name to be able to them. Your function won't come to you unless you call their name.

//We have our custom function.
function myFunction() {}

//We use it by calling its name and make it run using invocation token.
//Name: myFunction
//Invocation: ()
myFunction();

You need to set a number inside the parameter of the function. Meaning you need to put a number inside the brackets for the function to work. Otherwise the function has no number to work it's magic on.

//calling the function

random_age(25);
