Press STAT, go to Edit, then enter x values in L1 and y values in L2 (other lists can be used too, but these are the default ones).

Next, go to STAT PLOT, pick a plot, turn it on, select the type, data lists (x and y should be L! and L2 already; if not, change them), and mark type.

Finally, hit graph. You may need to adjust window settings to see all of the points. If you get a DIM MISMATCH error, check to make sure that there are the same number of entries in each list, and that only the plots that you are using are turned on.

    That should be L1, not L!. This site needs an edit button.

When I try and graph on my TI-84, "ERR: INVALID

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

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.
Happy Calculating

TI 84 won't graph more than one function. How do you change the settings so more than one function will graph at once?

If you have used or just run the Transfrm Application, you will no longer be able to draw more than one graph.
To restore the native OS graphing capabilities Uninstall the Transfrm Application. Here is how to do it.
  1. Press the [APPS] key.
  2. Scroll Up to reach the bottom of the list faster.
  3. Point to Transfrm and press [ENTER].
  4. Select [1:Uninstall]
Note: Do not worry about Uninstall, it will merely kick the application from memory. Transfrm will still remain in calculator.

Can the TI 84 calculate second derivatives?

I am sorry to disappoint you, the nDeriv ( function can only calculate numerical derivatives of an expression at a point. The dy/dx can do the same thing (calculate the first derivative) at one point on a displayed graph. It can be activated for graphs by pressing TRACE, then [2nd][CALC][6:dy/dx]. If you need the derivative at more than one point you have to press [2nd][CAL] [6:dy/dx] again.

What I said above concerns the native abilities of the calculator. There may be applications you can install to allow computation of 2nd derivatives. look for them on the TI site, or the archive section of Try deriv

Hope it helps.

Dim Mismatch

That is because you don't have the right amount of points. Either delete one point or add another point. Then try to graph it.
