Graph Function

Entering Equations:

When you enter the graph function, the graph edit screen is up. Type in an

equation using the XT or the letter X button for the variable X. You can change

the Y= to an inequality by pressing F3(TYPE) before entering in the equation.

Press F6 for more options for the equation. Press EXIT to get back out to the

original options. Press F6(DRAW) to see the graph.

View of the Graph:

If the graph cannot be seen, press SHIFT F3(V-window). Press F3(STD) for a

standard 20-interval view, press F1(INIT) for initial settings, and F2(TRIG) for a

standard trigonometry function. You may also set the setting manually and store

that setting by pressing F4(STO). Press EXIT to get back to the graph-edit

screen. You may view more than one graph at a time by pressing F1 on each

graph you want to show. This is how you can solve systems of equations.

Dual Screen:

In the graph function, press SHIFT(SETUP). Arrow down to Dual Screen and

switch it to Graph by pressing F1. Press EXIT to get to the previous screen.

Notice when you press DRAW, whatever picture of the graph was last seen will

be on the left, and the frame on the right will be blank. Zoom in on the graph

and that part of the graph will show up on the right. You may also use the dual

screen for a graph and a table. Go into the setup again and change the dual

screen to G to T for Graph to Table. Press EXIT to get back to the edit screen.

The graph will appear with a blank table. Press SHIFT F1(Trace) to trace values

on the graph. To put those values in the table press EXE. Put multiple values in

the table by pressing EXE repeatedly.

Solving for a Specific Point:

After you graph two inequalities you can find the point of intersection of those

graphs by using the

G-solve function. Press F5(G-Solv) (you do not have to press

the SHIFT key if the graphs are already on the screen). Press F5(ISCT). The

calculator will think for a few seconds and then trace the graph to the

intersection point for you. You can also find the roots, maximum, minimum,

y-intercept, y and x coordinates for given values, and definite integrals.
