**Damon**, Wednesday, May 14, 2008 at 6:31pm[x^.5 -3] / (x-9) is of course 0/0 so use

derivative of top/derivative of bottom

= [.5 x^-.5 ] /1

= as x-->9

[.5/3 ]/1

= .16666666666666.......

check

let x = 8.9

x^.5 -3 = -.0167

8.9-9 = -.1

ratio = .167

let x = 8.99

x^.5 - 3 = -.00167

8.99 - 9 = .01

ratio = .167

sure enough
