Notice something?
OpenStudy (anonymous):
xD it's not A hun
OpenStudy (anonymous):
soo.. its b.
OpenStudy (anonymous):
aha xD why do you thinl its B
OpenStudy (anonymous):
g(x) = x/1-X
f(x) = x^2-1
So x^2 + x = 2x^2
f(g(x))= -1 +2x^2/(1-x)^2

Ohh i wrote it wrong /_\
I would write it as
f(g(x))=x^2/(1-x)^2 , -1
OpenStudy (anonymous):
thanks for the help now i know why my answer was so way off.
OpenStudy (anonymous):
Oh wait you were right, f(g(x))=x^2/(1-x)^2 , -1 ... sorry i was thinking of a different problem
OpenStudy (anonymous):
well i just submited B. as the answer turns out it was right.
OpenStudy (anonymous):
It was b, I over thinked it.. like usually. the x^2 goes in the bottom, where (-1 -x)^2
