1. a. lim (-15)/((x^3)(x + 8)^4) = ?
x→-8-
b. lim (-15)/((x^3)(x + 8)^4) = ?
x→-8+
c. lim (-15)/((x^3)(x + 8)^4) = ?
x→-8
2. I don't think I've ever done a problem like this before...
I saw on one website (http://openstudy.com/updates/4f7761e7e4b0ddcbb89dced0)
that this person advised to replace the x→-8- with h→0.
He/she said to make x = -8 - h.
So, taking this advice, my problem is:
lim (-15)/[(8 + h)^3(-8 - h + 8)^4]
h→0
= lim (-15)/(-h^3 - 112h - 3h^2 -576)(-h)
h→0
Then I thought that I would replace the h's with 0's.
(-15)/(0 - 0 - 0 - 576)(0)
=-15/0 = Does not exist? :/
This is not right, I don't think.
Please help me to figure out this problem!
Thank you SO much! :)
