Question

25 POINTS PLEASE EXPLAIN AND HELP!!!!!!!!!

Find f(x) and g(x) so the function can be expressed as y = f(g(x)). y = Eight divided by x squared. + 4

Answer 1

Remark
You have been just a little bit ambiguous in your notation, those answering cannot be sure what you mean. A small hint. Certain mods will delete these sorts of questions.
I can't get the latex to work properly.

Condition 1
If you mean y = 8/(x^2 + 4) then
f(x) = 8/x
g(x) = (x^2 + 4)

Condition two
If you mean y = (8/x^2) + 4 Then
f(x) = 8x + 4
g(x) = 1/ x^2
