Best ResponseYou've already chosen the best response.0? Wouldn't it be a a denominator of 0, which is a "nono"?

Best ResponseYou've already chosen the best response.0if you get a zero in the denominator, but not a zero in the numerator, then there is no limit only when you get \(\frac{0}{0}\) can you continue if you get a zero in the denominator

Best ResponseYou've already chosen the best response.0l'hopital works for \(\frac{0}{0}\) in any case you didn't get there yet i am sure

Best ResponseYou've already chosen the best response.0So, @satellite73 would the limit be DNE ?

Best ResponseYou've already chosen the best response.0Because my teacher always says to only substitute directly when the denominator is not equal to zero...

Best ResponseYou've already chosen the best response.0not applicable here if you have a rational funciton, and you want to take the limit as x goes to some number, the first step is to plug in the number if you get a number back, that is your answer if you get \(\frac{a}{0}\) where \(a\neq 0\) there is no limit if you get \(\frac{0}{0}\) there is more work to be done factor and cancel but in this case you get \(\frac{4}{0}\) so forget it
