Answer:

f(x) = -4

Step-by-step explanation:

Given function: f(x) = 4 + 4x - 4x²

Here, we are being asked to find the value of the function when x is equal to 2.

Substitute 2 as the value of x in the function and simplify:

⇒ f(x) = 4 + 4x - 4x²

⇒ f(2) = 4 + 4(2) - 4(2)²

⇒ f(2) = 4 + 8 - 4(4)

⇒ f(2) = 4 + 8 - 16

⇒ f(2) = 12 - 16

⇒ f(2) = -4

This means that when the value of x is 2, the value of the function is -4.

Answer:  \textsf{f(2) = -4}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{f(x) = 4 + 4x - 4}x^2

Find:  \textsf{f(2)}

Solution:  We need to plug in the value of 2 into all of the x's that are present in the expression and then we just simplify the expression.

<u>Plug in the values</u>

  • \textsf{f(x) = 4 + 4x - 4}x^2
  • \textsf{f(2) = 4 + 4(2) - 4}(2)^2

Simplify the expression

  • \textsf{f(2) = 4 + 8 - 4}(4)
  • \textsf{f(2) = 12 - 16}
  • \textsf{f(2) = -4}

After completing the steps, we were able to determine that the answer to the question would be that f(2) is equal to -4.
