Hello!
I got the following exercise:
[tex]\frac{lim}{x\rightarrow6-}[/tex] [tex]{\sqrt{3x-18}}[/tex]
Now, since I need to evaluate the limit from the function coming from the left to the right that means that I can evaluate the function using x as a value very close to 6, but not six, right? So, since I would have a negative square root to evaluate then the limit does not exist, right?
But, how come when I evaluate that limit on my TI-89 calculator, and some online calculator I get that the limit is zero?
Can someone please explain to me what's going on? I'd be very appreciated. Thank you.
Edwin
