Question

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

y = Eight divided by x^2 + 4

Answer 1

what are you equations

Answer 2

your

Answer 3

This info comes from you, as no one else would know how f(x) and f(x) are defined.
What does the original problem statement say?

Your job is to find the "composition" of f(x) and g(x), which involves using g(x) as the input to function f(x).

Try it, please.

Answer 4

Well I had to find f(x) and g(x), but I got it now. So basically I had to figure out 8/x^2 is f(x) and g(x) =4 using the sum property. @mathmale
