please help
y=8/(x^2)+2

Answer 1

\[y=\frac{ 8 }{ x^2 }+2\]

Answer 2

if you set
\[g(x)=x^2\]
then
\[f(x)={8\over x}+2\]

Answer 3

you try to find the simplest repeating entity of "x"

Answer 4

so i would set x^2 at the numerator ?

Answer 5

for g(x)

Answer 6

yes g(x) is just x^2

Answer 7

\[f(g(x))=\frac{8}{g(x)}+2={8\over x^2}+2\]

oh ok now i see it :) thank you!:D
