if the limit value is always indeterminate?

Does it mean anything if the function limit is 0/0 after performing some algebraic manipulation? it still is indeterminate, right? and would i determine such by just graphing it or ?

You can test if a limit actually exists by computing one-sided limits. Example :

$\lim _{x\to 0^{+}}{1 \over 1+2^{-1/x}}=1$

${\lim _{x\to 0^{-}}{1 \over 1+2^{-1/x}}=0}$

If upper and lower bound are not equal then it simply doesn't exist.
