To transform the function \( f(x) = x^2 + 12 \) into \( f(x - 3) \), we want to evaluate \( f \) at \( x - 3 \).

We substitute \( x - 3 \) into the function:

\[ f(x - 3) = (x - 3)^2 + 12 \]

Now let's break down the operations needed to achieve this:

  1. Subtract 3 from x: This gives us \( x - 3 \).
  2. Square the result: We then square \( (x - 3) \) to get \( (x - 3)^2 \).
  3. Add 12: Finally, we add 12 to the squared result.

So, the correct order is:

  1. Subtract 3 from x.
  2. Square \( (x - 3) \).
  3. Add 12.

Therefore, the option that best describes the order of operations is:

Subtract 3 from x, square \((x - 3)\), and add 12.
