need help plzzzz will medal and fan

Stan evaluated a function with a value and got 3 as the result. He wrote the entire process as a sentence: The function f(x)=x^2+2x when evaluated with 3 gives you the value of 3 or f(x)=x^2-3x when evaulated with -3 give you the value of 3 or f(x)=x^2+2x when evaluated with -3 gives you the value of 3 or f(x)=x^2-3x when evaulated with 3 gives you the value of 3

The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3

Let's check all functions.
1. The function f(x)=x²+2x when evaluated with 3 gives you the value of 3:
  Evaluated with x means that x = 3.
   f(3) = 3² + 2 3 = 9 + 6 = 15 
   15 ≠ 3, so, this is not correct.

2. f(x)=x²-3x when evaulated with -3 give you the value of 3
    Evaluated with -3 means that x = -3.
    (f-3) = (-3)² - 3 (-3) = 9 + 9 = 18 
    18 ≠ 3, so, this is not correct.

3. f(x)=x²+2x when evaluated with -3 gives you the value of 3
    Evaluated with -3 means that x = -3.
    f(-3) = (-3)² + 2 (-3) = 9 - 6 = 3
    3 = 3, so this is correct.

4. f(x)=x²-3x when evaluated with -3 gives you the value of 3
    Evaluated with 3 means that x = 3.
    f(3) = (3)² - 3 3 = 9 - 9 = 0
    0 ≠ 3, so this is not correct.

Stan evaluated a function with a value and got 3 as the result. He wrote the entire process as a sentence:

The function [ \(f(x) = x^{2} +2\) ]

when evaluated with [ 3 ]

gives the value 3.
