Best ResponseYou've already chosen the best response.1no the one 11/6 is correct @Roya yes it means take the limit at infinity .

Best ResponseYou've already chosen the best response.1what if it say as x approaches to negtive infinity

Best ResponseYou've already chosen the best response.1its gonna produce similar result because the answer is depending on the coefficients of highest terms in both numerator and denominator .

Best ResponseYou've already chosen the best response.1lets say for this one. the first one: i got 2

Best ResponseYou've already chosen the best response.1but the second question asks: if it's coming from  infinity. @sami21

Best ResponseYou've already chosen the best response.1can someone explain why the negative infinity part right?

Best ResponseYou've already chosen the best response.1@sami21 i know it's 2 so how do we know it's 2? since i found the infinity part... and to find the negative infinity part would be.. ?

Best ResponseYou've already chosen the best response.0there is no different between + or  infinity. while solving these kind of question you ignore other part because infinity is so great. regardless it's positive or negative

Best ResponseYou've already chosen the best response.1so if i solved for infinity, an it asked me the infinity, the answer is the same?

Best ResponseYou've already chosen the best response.1as i mentioned above these limits depends on the coefficients of the highest terms in both numerator and denominator . lets give it a try divide both numerator and denominator with highest power (here it is simply x ) \[\Large \lim_{x \rightarrow \infty} \frac{ \frac{4+8x}{x}}{\frac{34x}{x}}\] \[\Large \lim_{x \rightarrow \infty} \frac{\frac{4}{x}+8}{\frac{3}{x}4}\] apply the limits \[\Large \lim_{x \rightarrow \infty} \frac{\frac{4}{\infty}+8}{\frac{3}{\infty}4}\] \[\Large \frac{0+8}{04}=\frac{8}{4}=2\]

Best ResponseYou've already chosen the best response.0just take care of function with different behavior along x axis . I mean the fuction which have different function for each of the X axis part dw:1375077760801:dw

Best ResponseYou've already chosen the best response.1@mathcalculus I hope its clear now . in these cases yes both in _ or  infinity answer remains unchanged . just look at the coefficients of highest terms .
