Answer: 9x^3 + 27x^2

Step-by-step explanation:

The given functions are

f(x) = 3x + 9

g(x) = 3x^2

To find (fg)(x), we would multiply both functions. It becomes

(fg)(x) = 3x^2(3x + 9)

We would multiply each term inside the parentheses by the term outside. We have

3x^2 * 3x + 3x^2 * 9

= 9x^3 + 27x^2
