what do u think so how we will start to solve it ?
OpenStudy (skullpatrol):
Any ideas?
OpenStudy (astrophysics):
Hint: \[y = \frac{ 8 }{ g(x) }+2\]
OpenStudy (anonymous):
I have to insert g(x) into the denominator?
OpenStudy (anonymous):
Ohhh wait the denominator is g(x)?

Yes, the goal of your question is to get a function represented as y=f(g(x))
OpenStudy (anonymous):
Okay, so i should write it as y(8(x^2+2)?
OpenStudy (astrophysics):
All you have to do is find f(x) and g(x)
OpenStudy (astrophysics):
So what is f(x) and what is g(x)
OpenStudy (anonymous):
g(x) is x^2 and f(x) is 8+2?

No...y = f(x) itself
OpenStudy (anonymous):
How do I write that?
OpenStudy (astrophysics):
\[f(x) = \frac{ 8 }{ g(x) }+2\]
OpenStudy (astrophysics):
You can see that y = f(g(x))
OpenStudy (anonymous):
Ohh okay so thats the answer?

or you can just write f(x) = 8/(x^2)+2
OpenStudy (skullpatrol):
y = 8/g + 2
Let g = ?
To get y = 8/(x^2) + 2
OpenStudy (astrophysics):
Yeah that's pretty much it
OpenStudy (astrophysics):
You have to write f(x) and g(x) but you already figured out g(x)
OpenStudy (anonymous):
So I should write down f(x) = 8/(x^2)+2?

So say f(x) =... and g(x) = ... and that's it
OpenStudy (astrophysics):
Yeah that's fine
OpenStudy (anonymous):
Okay, so what you first wrote down is the answer? I'm sorry i suck at this haha
OpenStudy (anonymous):
f(x)=8/g(x)+2
OpenStudy (astrophysics):
\[f(x) = \frac{ 8 }{ x^2 }+2\] 8/x+2 should work to I guess and you can write \[g(x) = x^2\] therefore it satisfies y=f(g(x))

Hmm yeah \[f(x) = \frac{ 8 }{ x }+2\] not x^2

Thank you sooo much!
