Question 77318
If the equation looks like:
{{{y=1/(x-2)}}}

<pre>

x  |  y
-1 |  -1/3
0  |  -1/2
1  |  -1
2  |  error - undefined. Since you cannot divide by 0, it is undefined
3  |   1
4  |  1/2

</pre>

{{{ graph( 300, 200, -6, 5, -10, 10, 1/(x-2)) }}} graph of {{{y=1/(x-2)}}}. Notice how there is no corresponding y value for x=2
