# Math Help - Incomplete graph..

1. ## Incomplete graph..

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

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.
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?

2. get out of that Zstandard window ... use Zdecimal, then shift the graph to the right by adding 3 to xmin and xmax.

When I graph the equation and then choose Zdecimal then the graph looks fine, but If I zoom out or expand the Ymax, I get the same result, the line is cut-off.
