Find f(x) and g(x) so that the function can be described as y=f(g(x)).Thanks!

Given:
We have
[tex]y=\frac{8}{\sqrt{2x+4}}[/tex]Required:
Select correct option.
Explanation:
We can check from D option
[tex]f(x)=\frac{8}{\sqrt{x}},g(x)=2x+4[/tex][tex]f(g(x))=\frac{8}{\sqrt{2x+4}}[/tex]Answer:
Option D is correct.
