Answer:

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

Step-by-step explanation:

In this question, we have that:

[tex]f(x) = x^2[/tex]

So, when [tex]x = 3, f(x) = f(3) = 3^2 = 9[/tex]

What is g(x)?

We have that [tex]g(x) = 3[/tex], when [tex]x = 3[/tex]

[tex]\frac{3}{9} = \frac{1}{3}[/tex]

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,
