How to Use the Basic Functions of a Graphing
Calculator. Going from a pocket calculator to a graphing
calculator can be as daunting as going from a skateboard to a car. Make the jump and learn the basics of using
a graphing calculator. You will need Graphing calculator and understanding
of the order of operations. Step 1. Turn on the graphing calculator by hitting
the On button and turn it off by holding down the 2nd key and pressing the On button. Step 2. Lighten and darken the screen by the pressing
the 2nd button and simultaneously pressing either the Up or Down arrow. Step 3. Use the multiple functions of the buttons. Press a button to use the function written
on the button, and hold the 2nd key while pressing a button to use the function written
above the button. Some graphing calculators also have a third
function that can be accessed by holding down the Alpha key while pressing the button. Step 4. Access the calculator’s menu by pressing the
button labeled Mode. Then move the cursor with the arrow keys,
pressing Enter to change settings. Step 5. Type equations on the main screen the way
they would look if you were writing them, and press Enter to display the answer. Follow the order of operations when entering
equations. Use parentheses to break up the equation in
the order each part should be solved. Operations inside parentheses are completed
first. Step 6. Erase unwanted items on the screen by hitting
the Clear button. Step 7. Graph an equation by pressing Y=. Then type the equation and press the Graph
button. Step 8. Adjust the picture of the graph by pressing
the Window button. Adjust the values of the x and y axes and
the x and y minimum to show key aspects of the graph. Did you know Casio produced the world’s first
graphing calculator, the fx-7000G in 1985.

  1. I have a TI-82 and when I try to put in the same equation she dis, y=4-6, then hit the graph button, mines say ERROR :STAT PLOT. Why does it do that?

  3. Yeah, right! And what major graphing calculator has Casio produced since the epic FX-7000G? The ClassPad was promising but didn't meet the expectations quite well. The design language is also very strange for what is considered a modern calculator, it looks like a bulky old PDA. It looks very dull and lifeless. It's unfortunate that they didn't build upon this "worlds first" technology. Texas Instruments has been dominating this domain for decades now.

  4. But the new Casio CG-20 is probably the most promising graphing calculator by Casio so far. Although I'm not sure if it can do CAS. It is not listed as a CAS capable calculator on their website. So that leaves us with the updated ClassPad 330.

  5. One question. When I want to graph something with a negative number in front of the operation like -16 x² +85 the calculator tells me ERR:SYNTAX … what should I do in that case?
