Question

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y=2/x^2 +9

Answer 1

you have lots of options for this
one could be \(g(x)=x^2+9\) and \(f(x)=\frac{2}{x}\)

Answer 2

I need an explanation to prove how they equal x. I know I need to plug them in, I just don't know exactly how @satellite73

Answer 3

what does "how they equal \(x\) " mean?
\(x\) is the variable

Answer 4

Sorry, I was thinking of a different problem im working on xD

Answer 5

if \(g(x)=x^2+9\) and \(f(x)=\frac{2}{x}\) then
\[f(g(x))=f(x^2+9)=\frac{2}{x^2+9}\]
