You could rewrite as:
Now, keep in mind that when finding the limit of a rational expression as , you can ignore everything except the highest powers.
I am very sorry with being so urgent, however I am having terrible trouble with my Calculus homework - can't figure it out at all and I am working for hours at it.
I have several problems that I may need help explaining. I would prefer not to just get the answer, and so would prefer just hints for now, however I really want/need to get full credit on this assignment, and I have a date set for 7 PM tonight.
Please help me
The first problem I have issues with is:
Find the limit of x approaches negative infinity of the function: ((10-15x)/(9+x)) + ((9x^2 + 13)/(12x-5)^2)
Thank you! How did you get that?! What was I doing wrong? I thought I was using the values correctly. EDIT: I realized that I used a positive 15 and you a negative, would that be because it is approaching negative infinity? If so, that was such a stupid error on my part as I had gotten 15.06... earlier.
And now time for the next question (there's a lot, so feel free to help only as much as you want to guys. I might start coming here frequently just so I can understand this stuff better)
((6x + 10)/(x - 7)) * ((7x - 2)/(-x - 8))
I got this one, was relatively easy after figuring exactly how I went wrong on the last one
