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.

The calculator has two minus signs
Examples. Let (-) be the negation and -- the regular minus.
You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.
You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.
I could go on with a few more examples, but that will take us away from your present concern.

Seems unlikely that you get a syntax error for both graphing and Zooming. Probably the error is in the function you are trying to graph.
To reset the RAM,
Press [2nd]MEM][7:Reset][1:All Ram][2:Reset] [ENTER]
Calculator answers with Ram Cleared.
Press [CLEAR] button to erase the above message.
Once Ram is cleared, open the [Y=] function editor and at the Y1= line, enter [X,T, theta, n] key or [ALPHA][X], to draw the simple function Y1=X.
If that works, that means your calculator is OK.
