Saving for a Rainy Day “How To”
The following will demonstrate how to enter a given formula into the GRAPH
module the Casio
fx-9750GII, graph the data, and use G-Solve to find x- and y-
values.
Example Formulas:
A =
n
n
r1
P

⎛
+
where n = 4, P = 100, and r = x
A = nP
(1+r)
n
where n = x, P = 1000, and r = 0.05
Steps for using the GRAPH Menu:
1. From the Main Menu, press
3 for the GRAPH icon.
2. Enter the first formula into Y1: by entering:
1000(1+fz4)^4l.
3. Enter the second formula into Y2: by inputting:
(fm1000)M((
1+.05)^f)l
.
To select the viewing window for the graph of this data:
1. Press the
B once, then press q to deselect Y2:
2. Press
u to display the graph of YI:.
3. Press
Lw(V-Window), theny(AUTO).
4. To see only the first quadrant, press
Le0l
N three times, 0thenl three times.
