Question

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

y = nine divided by x squared + 2

Answer 1

You could make this super easy by letting g(x) =
`x^(2) +2` and f(x) =
`(9)/(x)` and then the composition would be to take g(x) and put it into the x in f(x) to give you your
`(9)/( x^(2) +2)`
