Question

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

y=((4/x^2)+9)

f(x) = x + 9, g(x) = 4/x^2.

f(x) = x, g(x) = 4/x. + 9

f(x) = 1/x., g(x) = 4/x. + 9

f(x) = 4/x^2, g(x) = 9

I think it could be the second one but im not sure.

Answer 1

I want to see someone answer this. This looks new. ha. Looks to be lots of work.
