Question about Texas Instruments TI-84 Plus Calculator

1 Answer

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 <= y <= 3.5. The book then shows a picture of the line graphed properly. I have no idea how to set the less than or equal to limits for the x and y coordinates.

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.

How do I graph y = 5(x-10) and y = 3x on the same graph where x min = 0


Just open the Y= editor, and type in the two functions, one on each line. Make sure that the = signs remain highlighted when you move cursor on some other lines (Y3, or Y4).
Then open the Window utility and set Xmin=0
After graphs are drawn you can use the CALC utility to find the Intersection of the two lines.

How do you plot two liner equations on a ti-84?


I use one of the graphing APPS or do through a program. I have a users manual for TI 84 silver Edition that shows you how to archive\ unarchive to run programs here at this site. Usually, I tell people to just forget about the programs and use the simple concepts so, that they could operate their calculator better. But, if you notice in those program are actually more powerful than the programs you get on the web, because I wrote them to be flawless, or I only used programs that I knew would not clash and were very well written. Won't y1=(2/5)x-(11/5) and -3x+8 work?

y1=(2/5)x-(11/5) and -3x+8

i think there are programs but with something as simple as that you should be able to work it out manually....
3x+25-5x=5x-5x
-2x+25-25=0-25

Graph and trace buttons don't work


This is probably because you have the stat plot on. You would need to go to y= and then go to the top where it says stat plot 1 and un highlight it if it is highligted. That should fix your problem.

Graph and trace buttons don't work


If either error occurs when trying to graph a function (not a STAT PLOT), the error can be corrected by turning off the STAT PLOTS. The following steps will turn the STAT PLOTS off, allowing the graph of the function to be displayed.• Press [2nd] [Y=] to access the STAT PLOTS menu.
• Select 4: PlotsOff.
• Press [ENTER].
• Try graphing a function like y = x^4-3x^3+6x-1
