F(x) = x^2. What is g(x)?<br><br> pls help
LUCKY_DIMON [66]

Answer:

A. g(x)= 1/3x²

Step-by-step explanation:

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

So

  • g(3) = 3

<u>Let's check which of the answer choices is correct:</u>

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

<u>B. g(x)= (1/3x)²</u>

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

<u>C. g(x) = 1/9*x²</u>

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

<u>D. g(x)= 3x²</u>

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

<u>Correct choice is</u> A. g(x)= 1/3x²
