4. Tap the Graph window to make it active. Next, tap [Analysis] and then
[Trace].
• This causes a pointer to appear on the graph.
5. Use the cursor key to move the pointer along the graph until it reaches a
point whose coordinates you want to input into the table.
6. Press
E to input the coordinates at the current cursor position at the end
of the table.
7. Repeat steps 5 and 6 to input the rest of the coordinates you want.

1. In line y 1 of the Graph Editor window, input and save x 2 – x – 2, and then tap $.
2. Tap [Analysis], [Sketch], and then [Inverse].
• This graphs the inverse function. The message box briefly shows the inverse function.
Tip: If a function does not have an inverse, the graph produced by the [Inverse] command will be the result of
interchanging the x and y variables of the original function.

1. While the Graph window is active, tap [Analysis], [Sketch], and then [Circle].
• This display “Circle” on the Graph window.
2. Tap the point where you want the center of the circle to be, and then tap a second point anywhere on the
circle’s circumference.
• This draws the circle, and the message box shows the function for the circle.
• You can also draw a circle by specifying the coordinates of its center point and specifying its radius value.
In place of the operation in step 2 of the above procedure, press a number key on the keypad. On the
dialog box that appears, enter the required values and then tap [OK].

1. While the Graph window is active, tap [Analysis], [Sketch], and then [Vertical].
• This display “Vertical” on the Graph window.
2. Press
2.
• This displays a dialog box for specifying the x -coordinate of the vertical line, with 2 specified as the
x -coordinate.
• Instead of inputting a value here, you can use the stylus to tap the point through which the vertical line
should pass.
3. Tap [OK].
To draw a horizontal line, tap [Analysis], [Sketch], and then [Horizontal] in place of [Vertical] in step 1 of the
above procedure. In the case of a horizontal line, you need to specify the
y -coordinate in step 2.
