anewbie Group Title evaluate limx->3 (sqrt{x^{2}+7}-16)/x^{2}-3x one year ago one year ago

1. anewbie

$\lim_{x \rightarrow 3} (\sqrt{x^{2}+7}-16)/ x^{2}-3x$

please verify the question again ?

3. hartnn

because that limit does not exist. if thats correct, then you need to find left hand limit and right hand limit separately.

4. anewbie

the question is just this. i did does not exist but the answer is 1/10 :/

5. hartnn

umm..then there is something wrong with the question, what you have posted, the limit DNE. http://www.wolframalpha.com/input/?i=lim++x-%3E3++%28sqrt%7Bx%5E2%2B7%7D-16%29%2F%28x%5E2-3x%29
