## keeponbleeding How do I find f(x) and g(x) so the function can be expressed as y = f(g(x))? y = 8/(x^2) +4 one year ago one year ago

1. amistre64

there are a few ways this can be approached

2. amistre64

one way is to replace the "x" term with g(x) f(x) = g(x) + 4 then define g(x) by what was replaced

3. Zekarias

@amistre64 what if $f(x)=\frac{ 8 }{ (g(x))^{2} }+4$

There are a few ways to approach this like @amistre64 said.
