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 function set equal to zero. You may begin

inputting data into Y1: and press lto store. To draw your function, select u.

You can change the type of graph (r = polar coordinate, parametric functions, x =, and x-

and y-inequalities) by select the corresponding function button and then press the $to

begin inputting information.

1. To draw the graph of the function from the Icon Menu system, input

the following:

3x5x2y 2

32fs-5f-3l

To analyze features of this graph (roots, maximum and minimums, y-intercepts,

intersections, determine coordinates, and integrals) select y(G-Solve).

2. q(Root):

Note: The left-most root will always display first. Select$to display the next

root.

3. e(Minimum):

Note: As long as the x-value of your vertex is in the viewable domain; you do not

need to see the vertex to calculate the minimum value. However, you can

change the viewing window by selecting ein the graph window. You can

also change the window manually by using the!$BN.

4. r(y-intercept):

5. q(y-calculation): What is the value of y when x is 5



6. w(x-calculation): What is the value (s) of x when y is 1?

7. e(integral): Determine the integral value at (0,3) for the function .

functions or rto change a previously entered function to an inequality.

1. To see a table for the function 4x

y , highlight Y1: and input the following

2z3f-4lu

2. The default setting for tables is: X starts at 1, ends at 5, and increases by increments

of. You change this by pressing dor q(FORM) to return to the initial screen

and then select y(SET).

3. However, you can manually enter a number anywhere in the x-column of the table

and presslto see the corresponding y-value (including fractions, decimals, even

). You can insert and delete rows in this view by pressing e(ROW).

4. From the table view screen, you can press y(G-CON) to see a linear graph or

u(G-PLT) to see a plot graph for the function you entered.

STATISTICS

This section is an overview of the STAT icon; it will highlight just a few of the features for

single-variable data and paired-variable data. To select this icon, you may highlight it and

presslor press2.

The initial List Editor Screen that allows input of statistical data and performs numerous

statistical calculations. To input a list of single-variable data, highlight the first cell under

List 1 and enter each number followed by l.

1. For this example, input this set of data:

1, 0.5, 1.2, 4, -1, 1, 3, 5, 6, 3.4

2. From this screen you display various graphs depending on whether you single or

paired-variable data (scatter-plot, line, normal probability, histogram, median box,

mean box, normal distribution, broken line, and regression: linear, quadratic, cubic,

quartic, logarithmic, exponential, power, sinusoidal and logistic).

3. The initial default graph is a scatter-plot. To change the type of graph you would

like to use, press q(GRPH), then u(SET), Nto Graph Type:, for this set of data,

we will make a histogram, press u, and then qfor histogram.

Casio “The Basics fx-9750GII” 9

4. Press dto take you back to your list of data and select q(GPH1) and then lto

see your graph.

5. The following screen shots show what one-variable calculations can be obtained by

pressing q.

6. To delete this set of data, press duntil you return to the initial List Editor screen.

Select ufor more options, arrow up until List 1 is highlighted, select r(Del-A),

then q.

7. For paired variable data, use the following:

List 1: 0.5, 1.2, 2.4, 4.0, 5.2

List 2: -2.1, 0.3, 1.5, 2.0, 2.4

Enter List 1 first, and then $to begin entering List 2.

8. To see a scatter-plot of these data, you can go through and change back GPH 1

using the process above, or select w(GPH 2) from the List Editor screen whose

default is also a scatter-plot.
