i wrote my answers thrre but im not sure if theyre correct

no the one 11/6 is correct @Roya yes it means take the limit at infinity .

what if it say as x approaches to negtive infinity

sami21Best ResponseYou've already chosen the best response.1
its gonna produce similar result because the answer is depending on the coefficients of highest terms in both numerator and denominator .

can someone explain why the negative infinity part right?

@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.. ?

there 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

so if i solved for infinity, an it asked me the infinity, the answer is the same?

as 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 \[\Large \lim_{x \rightarrow \infty} \frac{\frac{4}{\infty}+8}{\frac{3}{\infty}4}\] \[\Large \frac{0+8}{04}=\frac{8}{4}=2\]

just 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

@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 .
