Lesson 4
Getting Started (Introduction to Graph & Table, continued)
Focus is the key! Without it, having two windows open in the ClassPad would not make sense. You will understand this by the end of part 1. Focus is extremely important.
Part I
In this part, you will learn about window focus and graphing in general.
1. Window Focus
[Very Important]
Which window are you in? You are in the one with focus!
- We say that the active window, the window with a bolder edge (border), is the window with “focus”.
- To change focus to another window, just click inside it.
- Remember that the toolbar and menu are specific to the window with focus AND its outer edge is bold.
- If you can’t find a particular button, make sure the correct window has focus!
2. Graph & Table
3. The Graph Editor Window and Graph Window
The Graph Editor allows us to input, graph and analyze equations.
4. Line Style and Inequalities
5. Finding Points of Intersection
6. Using the Table

- Re: Lesson 4
- Please open the Graph & Table application and clear the window.
- Graph y1=x^3+3x^2-1.
- Resize the Graph window (you can click Resize or press Ctrl+r).
- Get a screen capture and paste it into your Lesson4 document (under a title of PART I).
- Click Resize or press Ctrl+r again.
- Input y2 = 2x+5 and then graph y1 and y2.
- If you do not see three intersections, open the Zoom menu and select Quick Standard.
- Find each intersection.
- Use the arrow keys to move between the intersections (either direction).
- Get a screen capture while the intersection with xc=1.4142135 is showing. Please add two blank spaces following the first screen capture and paste this one.
- Open the Table window.
- Change the table values to start at -20 and end at 20.
- Set the table step size to 2.
- Get a screen capture with your table showing. Add two spaces following the last screen capture and paste this one. Thank you.
