Need a better explanation

Need a better explanation

Hi Brian,

Your hint and your solution is definitely right telling students what to do. But to me, it didn't explain why they are doing that. I think it is better to explain the definition of vertical (undefined points) and horizontal asymptotes (existence of limit as x goes to infinity) , so they won't get lost when they encounter a more complicated question. What do you think?


Best,

Hi Han,

Thanks for the feedback, you might be right. However, the hint and solution for this question has already been approved by another reviewer (status for both is QG), so it may be a bit awkward for me to make further revisions to this question.

Dear Brian,

Never mind, I just expressed my opinion, it doesn't really matter if students don't get confused themselves.
