**Damon**, Friday, December 19, 2008 at 9:59pmI bet you mean

y = 5/(x-3) ????

if so then

approches zero at - infinity and + infinity

undefined at x = 3

negative between x = -oo and x = 3

positive between x = 3 and x = +oo

decreasing for all x except exactly as x = 3

In other words goes down from 0 to -oo as x goes from -oo to 3

then goes down from +oo to 0 as x goes from 3 to +oo
