Answer:

B g(x)= 1/3x^2

Explanation:

In this question, we have that:


f(x) = x^2

So, when
x = 3, f(x) = f(3) = 3^2 = 9

What is g(x)?

We have that
g(x) = 3, when
x = 3


(3)/(9) = (1)/(3)

This means that g is a third of f, and the correct answer is given by option B.

It is not d because the paranthesis is elevated, which means that (1/3)^2 = 1/9,
