My TI-84 will graph but it will not show me the table of values. It just shows up blank.


Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg. If you want both graph and table side by side use the split screen feature.
To do so press [Mode]. Scroll down to the last line Full Horiz G-T. Highlight the option G-T. Press the Graph key.

How do I graph sinx on my Casio fx-9750GII calculator?


Turn calculator ON
If you see no icons, press Menu
Press 3 (Graph) draw your function. (more on that later).
If the first line of the display show Graph Func : Y= you should be able to draw your function.
If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.
After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.
Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.

Graphing doesnt show


Depending on the function you are drawing, it is possible that the graph is out of range of the windows dimensions. Try Zooming out to see a bigger portion of the plane. If you know where the function intercepts one of the axes, you might want to center the graph around that point.

When graphing the function (x+6)/(x-7) I'm getting a vertical line showing up on the graph connecting the two curves that shouldn't be there. do I have something turned on that shouldn't be?


The vertical line is called an asymptote, it is not connecting the graph, it means that the function goes to infinity as the function nears the line. In this case the graph goes to infinity and negative infinity as the x nears 7. This is because the function becomes undefined at x = 7 , plug 7 into x and we get 1/0, dividing by zero is undefined. Thus, the calculator puts the vertical asymptote in the graph to symbolize the action of the function nearing infinity.

Graphs on some TI-84's and TI-83's appear connected where asymptotes should be, like f(x) = 2/(x-squared - 1). Most don't show these connections. How do I get rid of them.


I have drawn the curve for your function. On my TI84Plus with OS version 2.53MP the spurious asymptotes do not show, while on a TI83PLUS OS 1.12 they do if the graph is drawn as connected lines. It might be a bug that was corrected in newer OS (for TI84PLUS)

The graph from a TI83PLUS (the last one above) shows asymptotes when drawn connected, but no asymptotes appear if graph is drawn dotted.

Doing precal work, graphing a problem, (3x^2-3X)/(x^2 x-12). The TI 84 does not show what actually happens as the graph crosses the (6,3) point. The book says to graph it for -4 <= x <= 60 and 2.5...


You need to adjust the range of your graph. On the graph menu press range then enter the values of x and y. Set Xmin to -4 and Xmax to 60, and ymin to 2.5 and ymax to 3.5. IThis should adjust it properly, as you say.

Won't Graph Exponential Function


Ok, try these two things and you should be just fine.
1.) Check your range for your graph. It is possible that the range you are using isnt large enough to show the curve. Also try using Z-fit vs Z-st. These are options that your calculator will give you once the equation is graphed.
2.) Place a parenthesis around the 2x, make sure that you and the calculator are both using the same order of operations. This move mill ensure that the calculator will multiply the variable, x, by two and then do the exponential.
This should do it!
Happy Graphing!
