I don't know how to graph absolute value functions on Casio fx-9750GII.

In statistics, the range of 1-var a data set is the difference between the largest value and the smallest. R=Xmax-Xmin
In functions: the range of a function is the interval (or the Union of intervals) of the real line where the dependent variable takes it values.
Ex: sin(x). Whatever the value of the independent variable x, the values of the function sin(x) are in the closed interval [-1,1]. The range of the functions sin(x), and cos(x) is [-1,1].
No use of a calculator for finding the range of functions.

To access the absolute value command, got to Run/Mat screen and press OPTN. Press F6> the F4:NUM, then F1:Abs
In the Y= entry screen, press OPTN, then F5:Num, F1:Abs. enclose the argument of the function inside parentheses.
Here are two screen captures to show how it is done.

To use the asolute function you go to the RUN screen, press OPTN, then F6> to ge to next screen with a TAB called NUM. Press F4 to open the NUM tab. The Abs function is above the F1 key. See the screen capture to help you for graphing.

If you want to graph the absolute value of a function, feed the function to the absolute value ie graph y= abs(f(x)). The calculator will take care of it. See screen captures where I draw the function y1=x^3-5x^2-3 and y2='x^3-5x^2-3'. On the first graph the function is represented and on the second the function and its absolute value.







The calculator knows how to calculate the absolute value of an expression. The name of the command is abs(

You'll find the absolute value function in the MATH menu.

Sorry but you cannot do that. This is not a graphing calculator. However you can generate a table of values for your function (MODE TABLE) and use it to graph the curve by hand (pencil and paper).

If you need a Casio graphing calculator, one of the cheaper ones is the Casio FX-9750GII. Equivalent Texas Instruments calculators are the TI83PLUS/TI84PLUS.

Hey it is. Okay, so start with a equation: say, y = -(1 |x|). Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this. y = -(1 Abs (x)) then graph it.

The absolute value button is "SHIFT", "Abs" (located on the "hyp" key)
