To find \( f(-2) \) for the function \( f(x) = 3x^2 - 6x + 2 \), we will substitute \(-2\) for \(x\):

\[ f(-2) = 3(-2)^2 - 6(-2) + 2 \]

Calculating each term step-by-step:

  1. \( (-2)^2 = 4 \)
  2. \( 3(-2)^2 = 3 \cdot 4 = 12 \)
  3. \( -6(-2) = 12 \)
  4. Now substituting everything in:

\[ f(-2) = 12 + 12 + 2 \]

  1. Combine the values:

\[ f(-2) = 12 + 12 + 2 = 26 \]

Thus, \( f(-2) = 26 \).

Since none of the provided options match 26, it's possible that there was an error in the options. Double-check that you've provided the correct function or choices. If none were incorrect, the computed \( f(-2) = 26 \) is accurate based on the given function \( f(x) \).
