Question 104146: Please Help me solve this problem
f(x)=5x^2-8x
g(x)=x^2-3x-40
Find f/g(x)
I know that you set the problem up like this
(f/g)(x)=5x^2-8x/x^2-3x-40
I am not sure if it can be factor or not??
If it can please show me the steps on how it is done and what the answer
should be?
Thank you so much

Question 104163: the Question is: 100.)(2x+3)/(x^2+x+3)
Find the Domain of the function, and identify any horizontal and vertical assymptotes.
I have the following:
Domain: all real numbers???
Horizontal assymptote at x=2
and I used the quadratic formula for the vertical assymptote and found imaginery assymptotes. AThis is where I got Lost!!

Question 104165: the problem is 2x^3+3x^2-2x-3/x^2-3x+2
"check for intercepts, vertical assymptotes, horizontal assymptotes, slant assymptotes, and holes.
I have:
slant assymptote at 2x+9=y
vertical assymptote at x=2 and x=1
No horizontal assymptotes
Domain= all real numbers
No hole in the graph

Question 104415: how do you figure out the equation for rectangular numbers?
ex. the first term is 1, there are 2 dots, the second term is 2, there are 6 dots, the third term is 3, there are 12 dots.
I see that the first difference is 2 more than the previous, and the second difference is 2, but how do i write this in an equation? Thank you.

Question 104881: I am having a hard time with functions, I need help on setting them up.
Given f(x) = –x3power – x2power + 2x – 8, find f(–1), f(0), and f(2)
Given f(x) = –5x – 1, find f(a – 1)
Given f(x) = –2x – 4, find f(–3)
Thanks so much, I am stressing out over this math.
