MATH110/April 2017/Question 04 (b) (ii)

Hi Aili,

It would be great if you explain why the limit goes to infinity. (you can explain the denominator goes... and the numerator goes.... , so ....) As I mentioned before, we should provide more explanatory solutions for MATH110 students.

Also, please explain why you consider $x\to 0$ only. (In other words, why the other points are not the candidate for vertical asymptotes. )

It would be helpful if you recall the definition again.

Thanks,
