What is a function?

In this activity, whenever you see 💬, stop and share your responses with your partner. If you have different responses, try to come to a consensus.

In the first activity, you may have noticed that all of the simulation screens share a three-part structure. These three parts can be described in a variety of ways, such as the ones listed in the image below.

1. Come up with your own names or labels for the three parts of a function.

2. Share your labels with your group. Write down any similarities. 💬

For questions 3 – 4, use the following instructions.

Use the simulation screen labeled “Patterns”. Note you can switch between simulation screens using the toolbar located below the function builder.

3. The blue “builder” in the middle of the screen is a function. Describe what a function is using the labels you've agreed on as a class. 💬

4. Suppose you build this function:

  1. a. Complete the following table, sketching what happens after going through the function.
    Input Output
  2. b. Write a rule that describes what the function does. Compare with your group. 💬
