The prompt says "Graph each function. Determine the interval[s] for which the function is increasing and the interval[s] for which the function is decreasing."
The problems that are given in this prompt are:
1. y= x^3+3x^29x
2. f(x)=1/(x+1)4
3. g(x)=(x^2+5)/(x2)
I need mega help..

how far along are you? Can you tell when a function is increasing or decreasing?
First step: try sketching the graphs as asked. You've had a couple of years of algebra now, so you should be able to find roots, asymptotes, etc.
You can also visit
rechneronline.de/functiongraphs/
for some excellent help. Play around there and get a feel for how these functions work. 
I got the first one. I guess what I don't understand is the Asymptotes. Do I include them in my answer?
Cause, I feel like they have to be included.
