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

the end of f(x) would have +3...so would f(x) be (1/x^2) +3

Answer 2

you have lots of ways to do this

Answer 3

ok...well what i wrote.. is it right?

Answer 4

it is
\[y=\frac{2}{x^2}+3\]?

Answer 5

yes

Answer 6

you need to write both an \(f\) and a \(g\) to answer this

Answer 7

i know but does my f fit?

Answer 8

here is one example
\[g(x)=x^2,f(x)=\frac{2}{x}+3\]

Answer 9

you will need to put a \(+3\) at the end of \(f\) yes, that is a must

Answer 10

as a matter of fact, you could just write \(f(x)=x+3\) and then \(g(x)=\frac{2}{x^2}\)

Answer 11

I understand! so another answer may be, f(x)=x+3 and- ...iw as about to say that

Answer 12

yeah that would work lol

Answer 13

haha XD thanks
