Construct graphs of functions

[dhevian]

Hello,
I have to tasks to solve and i would really appreciate if someone would help me solve them.

Construct graphs of functions for derivative functions. I know there are several steps to do that but i didn't learn it yet.
y=21-x^2/(7x+9)


y=x^4/(1+x)^3

Does solve mean graph? If so, why not say that? I would 1st divide x^2 by (7x+9)

Do you mean 21- (x^2/(7x+ 9)) (as you wrote) or (21- x^2)/(7x+ 9)?

y=x^4/(1+x)^3

Are you asked to graph these or to graph their derivatives? In either case, each will have a vertical asymptote. Can you tell where?
