Question

F(x) = x2 What is g(x)?

A g(x)=3x^2
B g(x)= 1/3x^2
C g(x)= 1/9x^2
D g(x)= (1/3x)^2

Answer 1

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,
