Not sure where I made the mistake?
1. for f(x)=[2x-4]/[x^2-x-2], which of the following is true?
I. f(x) has no relative extrema
II. There are vertical asymptotes at x=2 and x=-1
III. There is a horizontal asymptote at y=0
My answer:
Only II & III because i don't get how one is right?
what I did was:
f'=[2x^2+8x-8]/[x^2-x-2]^2
is that the right answer for the derivative? because if it is, wouldn't u be able to find x by setting the top part = to 0?
