Lesson 4

Part III (Introduction to Graph & Table, continued)

In this part, you will learn how to graph equations other than y as a function of x. You may remember that an equation is a function if each input produces exactly one output. If you have not learned about functions yet, you will someday. For now, let’s begin graphing different types of curves that may or may not be functions!

The on the Graph Editor toolbar opens a button palette that contains a button for each item in the Type menu. We can graph many different types of curves in the same window. The type of graph we choose will change all graph positions that are empty.

1. Graphing with y= and x=

Practice Exercises

  1. Start by clearing the Graph Editor’s window. Remember, this is fun!
  2. Click to maximize the Graph Editor window.
  3. Duplicate the given equations. Remember to look in the keyboard to find special characters and in 2D math for special symbols.
  4. Graph your equations and then select Zoom/Square.
  5. Resize your window. If you input the equations correctly, your graph will look like this:
  6. Get a screen capture and paste it into your Lesson4 document (under a title of PART III).
  7. Open the menu and select Graph Format. Change the settings to match the ones below. Click the Set button to save the changes and exit.
  8. Get a screen capture. Add two blank spaces following the last screen capture and paste this one.
  9. Open the Graph Format dialog again.
  10. Click the Default button and then the Set button.
  11. Resize your window and uncheck y5
  12. Graph your equations again.
  13. Get a screen capture. Add two blank spaces following the last screen capture and paste this one.

Reflection Exercises

You have just completed the fourth lesson in ClassPad 101. The Graph application is very useful. Please take a few moments to copy and paste the following three questions at the end of your Lesson4 document and answer them.

  1. Approximately how long did it take you to complete this lesson?
  2. Which activity did you enjoy the most?
  3. Did you find any part of this activity difficult to follow? If so, which part? Also, how did you overcome the difficulty?
