Find f(x) and g(x) so that the function can be described as y = f(g(
y = four divided by x squared. + 9
f(x) = x + 9, g(x) = four divided by x squared.
f(x) = x, g(x) = four divided by x. + 9
f(x) = one divided by x., g(x) = four divided by x. + 9
f(x) = four divided by x squared., g(x) = 9

Listed below

Step-by-step explanation:

This is a function composition excercise. The idea is to sustitute the value of G(x) in the X's value of the other function.

a) and

So we replace g(x) on the X of the f(x) function and we get:

b) We do the same on this excercise:

and " alt="f(g(x))=\frac{4}{x+9}" />" />

We replace and we get:

c) And the same on this one:

and

We replace and we get:

d) Exactly the same on this excercise:

and

We replace:
