(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

lim sqrt(x^2-9)

x->3

2. Relevant equations

I understand that the radical will evaluate to 0. I am not sure if the answer to the limit is 0, or undefined

3. The attempt at a solution

lim sqrt((3)^2-9) = sqrt(9-9) sqrt(0) = 0

x->3

Thanks for your help.
