I have the answer can someone just see if I'm right.
f(n)=3n^2-2 and g(n)= n+1
The domain of f(n)/g(n)

ok
OpenStudy (anonymous):
I am not sure if I did it right do you have an answer
OpenStudy (anonymous):
you are trying to find the domain of a rational function right
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
from what i can see your domain is every value apart from -1

because -1+1=0, that will lead to the 1/0= undefined at ur level
OpenStudy (anonymous):
so -1 does not satisfy this equation
OpenStudy (anonymous):
So is the answer then just 3n^2-2
OpenStudy (anonymous):
no dear
OpenStudy (anonymous):
this is not about simplifying the expression

this is about what numbers can i plug in n
OpenStudy (anonymous):
yes it is Find and simplify
OpenStudy (anonymous):
Question is ((3n^2-2)/(n+1))
OpenStudy (anonymous):
yes from what i am reading its says find the domain
OpenStudy (anonymous):
That is true I am really confused right now

\[\frac{ 2n^2 -2}{ n+1}\]
OpenStudy (anonymous):
don't be
OpenStudy (anonymous):
Put a 3 instead of a 2 for 3n^2
OpenStudy (anonymous):
\[\frac{ 3n^2 -2}{ n+1}\]
OpenStudy (anonymous):
yes sorry it would have been easier if it was 2 anyways

Yes that is the equation now find and simplify also The doamin of f(n)/g(n)
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
Do you have an answer so I can see if it matches mine
OpenStudy (anonymous):
i gave u the answer for the domain
OpenStudy (anonymous):
now u added a new part so i will solve it for u
