EL-9400 Graphing Calculator NotesKey OperationDisplay Example 5 Shift Graph shift function helps students grasp the relationship between an equation and its graph. Shift the graph’s location without changing its shape, and the change is immediately reflected in the equation on the right side of the display. When the graph of y = x2 is shifted downward, how does this affect the equation? Select the location of the shift: move cursor down twice. Enter SHIFT/CHANGE mode.1 2 3 4 5 Select shift. Cursor moves to the equation menu. Select the equation: y = x 2 and draw the graph. View the result of the shift. SHIFT/CHANGE (Change the location of graphs) y = x2 y = x2-2 Features If SHIFT is not already highlighted press .] ] ] ]

Change Graph change function helps students grasp the relationship between an equation and its graph. Change the shape of the graph, and the change is immediately reflected in the equation on the right side of the display. Enter SHIFT/CHANGE mode and specified ( CHANGE).1 3 4 5 2Select change. Cursor will move to the equation menu. Select the equation: y = x 2 and draw the graph. View the result of the change. Select the location of the change: increase the value of y- coordinates.

EL-9400 Graphing Calculator NotesKey OperationDisplay Example 7 Slide show Slide show assists with teacher preparation. By selecting from the built-in options or cre- ating your own series of slides, you can demonstrate lessons with minimum preparation time. Use the built-in slide show of y = x2 to show how the coordinates change as you move along the graph. Select y = x2 and the first slide appears. Moving between the values you can follow the changes in the graph’s coordinates, making the nature of the graph easier to understand.
