Practice Exercises

  1. Open the 2-D Graph application and clear its equations.
  2. Graph y1=sin(x).
  3. Change the line style of y1 and graph it again.
  4. Drag and drop the sin(x) to the small box following y2. Change y2 to 2sin(x), press Enter and click the graph button. Think about how the graphs differ.
  5. Change the line style of y1 and y2 so that they are different. Graph y1 and y2 again to see the line change.
  6. Add the title PART II to your Lesson1 document just below the three screen captures.
  7. Get a screen capture and paste it into your Lesson1 document (under the PART II title).
  8. Uncheck y1 by clicking on its check mark. Click the button for graphing. Notice only y2 is graphed.
  9. Uncheck y2 and then input and graph just y3 < 2x – 1.
  10. Get a screen capture. Add two blank spaces following the last screen capture and then paste this one.
  11. Uncheck y3.
  12. Input and graph y4=x^2– 4. Be sure to check the box.
  13. While the Graph window has focus, open the Zoom menu and select Quick Standard.
  14. Open the Analysis menu and select Trace. Move the cross-hair cursor around by pressing the left and right arrows on your keyboard.
  15. Get a screen capture. Add two blank spaces following the last screen capture and then paste this one.
  16. Spend a few minutes graphing. You can edit y1, y2 and y3, or enter different equations. Also, look in the Analysis menu (this is a very useful menu). Have fun!
