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 y1 of the Graph Editor window, input and save x

– 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.
