When I graph the function: $\displaystyle y=-2 log_3(x-3)-1$

On a java applet it looks fine, but on the TI-83 it terminates abruptly.

It only shows whole numbers when I view table on the TI-83. Since the asymptote is x=3, I'm missing some of the y values between x=3 and x=4.

There's no access to a table in the java applet.

When I transfer the points from the table onto paper, I have to manually enter x values to complete the graph, otherwise the graph looks incomplete.

Any tricks I can use there?
