Question

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).

y=(2/x^2)+3

Answer 1

\[y=\left( \frac{ 2 }{ x^2 } \right)+3\]

Answer 2

we can have
\[f(x)=\frac{ 2 }{ x }+3\]
and
\[g(x)=x^2\]

Answer 3

I've always been confused how we can have x^2 and an x, but when we combine, it isn't x^3....

Answer 4

Thanks!

Answer 5

well all you do is just replace x with 'new' x

Answer 6

Oh! I forgot about that! Thank You!
