Quick
Reference Guide
Selecting the RUN Q icon will allow you to perform
general computations and arithmetic.
The function keys allow you to access the tab (soft key)
menus that will come up at the bottom of the screen.
When an u appears above the u key, selecting u
will offer more on-screen choices.
The p key displays every mode the calculator has. To
select a mode, you may $B to the desired icon and
press l or press the number or letter in the lower right
hand corner of the icon.
The d key operates like the back arrow on a web
browser; it will take you back one screen each time you
select it. The d key will not take you to the icon menu.
The x key is a toggle key that will change answers or
entered numbers back and forth from decimal to fraction
form.
The O key will power the unit on. To turn the unit off,
press the yellow L key, then O key.
Thez key is used to obtain a fraction bar. To obtain a
mixed number, press z after inputting the whole number.
The l key executes operations. When data is entered,
the l button must be pressed to store the data.

GRAPH
Various icon (Run, Table, Dynamic, Recursion & Conics) will allow you to graph or analyze the
graphs of given information. This section is an overview of the GRAPH Icon and will highlight
some basic features of this mode.
The initial screen allows immediate input of functions set equal to zero. You may begin inputting
data into Y1: and press l to store; to draw your function(s), select u.
You can change the type of graph (r = polar coordinates, parametric functions, x =, and
y-inequalities) by selecting the corresponding TYPE button and then press the $ to begin
inputting information.
When the TYPE of graph is changed, it only effects the current line and entries below it.
Functions already stored are unchanged.
1. To draw the graph of the function y=2x
• 32fs-5f-3l
To quickly change your window, you can utilize the Replay arrows. Specic changes can be
made to the viewing window by selecting V-Win e.
To analyze features of this graph (roots, maximum and minimums, y-intercepts, intersections,
determine coordinates, and integrals) select y (G-Solve).
