There are several options for formatting the display screen when graphing functions. To access
these, go to the FORMAT menu. Press 2
the left column. To change any of these, arrow down to the line that needs to be changed, arrow
over and then press ENTER. Experiment with these to see the changes that can be made to the
graphing window.
Graph a function by entering the function in Y=. The graph shown is Y1 as entered in the earlier
examples. When TRACE is activated, the calculator places a cursor on the screen and reports
the x and y coordinates of the location of the cursor at the bottom of the spring. Also, the
function that is graphed is displayed at the top of the screen (if the default ExprOn is activated).
To move the cursor around the graph, use the left and right arrow keys.
If two functions are graphed, use the up and down arrow keys to toggle between the two
functions.
