My TI 84 plus silver: whenever I push the graph button the message ERR: Syntax 1:quit 2: goto appear on screen please help

Help lost my L1 or L2 on the Ti graphing calculator

Could you post the function you're trying to plot? Please give the exact sequence of keys you used to enter the function.

If I had to guess, I'd say you're using the "-" key when you should be using the "(-)" key.

Try rewriting your equations in the equivalent forms that follow.
Y1=3-X
Y2=(1-X)/3

If you do not get a syntax error it means that you were not using the correct minus sign.
If the - is the first symbol after the equal sign you must use negation (-) or change sign key.
Similarly, after the division / key you must use the negation or change sign (-)

Hello,
The easiest and quickest way to start graphing is to reset the RAM. Press [2nd][MEM][7:Reset][1:All Ram][2:Reset], then [CLEAR] to clear the RAM Cleared Message and go to the main screen.
Hope it helps.

How do I correct ERR: MEMORY on a TI-83 family or TI-84 Plus family graphing calculator?

An ERR: MEMORY is given when there is not enough memory to perform the instruction or function. To increase available memory by deleting the contents of any variable (real or complex number, list, matrix, Y= variable, program, Apps, AppVars, picture, graph database, or string), follow these steps. • Press [2nd] [MEM] to display the MEMORY menu.
• Press 2: Mem Mgmt/Del.
• Select a variable or data that needs to be deleted and press [ENTER].
• Use the arrow keys to move the cursor next to the item, and then press [DEL]. The variable or data should now be deleted from the memory.
When deleting programs or Apps, a message asking for confirmation will appear. Select 2:Yes to continue. To leave any variable screen without deleting anything, press [2nd] [MODE].
Notes:
With the exemption of programs and Apps, no warning will be given to verify the deletion.Some system variables, such as the last-answer variable Ans and the statistical variable RegEQ, cannot be deleted.

Hope it helps.

Press the 2nd Button then the ZOOM button. Make sure that AxesOn is highlighted. If not, move your cursor down until you on AxesOn and press ENTER.

If AxesOn is highlighted, then it is probably your window. Press ZOOM, then 6.

Press the 2nd button, then the plus button, the 7, then 1, then 2. This will reset your calculator.

Ok i had the same problem- If i remember correctly my "window" was messed up. Check it out... If not i always pull the "take batteries out while on" trick which resets the ram.

First, turn it on. Once the calculator is on, press the "2ND" key (I believe it is a blue key in the ti-84 plus silver edition). Now press the plus key (+). A little above that key, you should see the word "mem." When you see the screen titled MEMORY, move the cursor all the way down to the option that says "Reset." From here, you can choose to reset either the RAM memory, or the factory settings. The factory settings are the "Defaults" option. I hope this helps.
