Question

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

y = (8/x^2) + 4

How can I split it?

Answer 1

f(x) = x + 4
g(x) = 8/x^2

Answer 2

so f(8/x^2) = (8/x^2) + 4

Answer 3

ok thank you

Answer 4

you could say infinite answers
f(x) = x and g(x) = (8/x^2) + 4
or f(x) = x+-2 g(x) = (8/x^2) + 6
