Question

F(x) = x^2. What is g(x)?

pls help

Answer 1

A. g(x)= 1/3x²

Explanation:

The graph of the function g(x) has a point (3,3) on it.

So

• g(3) = 3

Let's check which of the answer choices is correct:

• A. g(x)= 1/3x²
• g(3) = 1/3*3² = 3
• g(3) = 3
• This is correct

B. g(x)= (1/3x)²

• g(3) = (1/3*3)² = 1
• g(3) = 1 ≠ 3
• Incorrect

C. g(x) = 1/9*x²

• g(3)= 1/9*3²= 1
• g(3) = 1 ≠ 3
• Incorrect

D. g(x)= 3x²

• g(3)= 3*3²= 27
• g(3) = 27 ≠ 3
• Incorrect

Correct choice is A. g(x)= 1/3x²
