To find \( f(2) \) for the function \( f(x) = 3x - 12 \), follow these steps:
1. Identify the given function and the value to substitute: The function provided is \( f(x) = 3x - 12 \). We need to find \( f(2) \).
2. Substitute \( x = 2 \) into the function: Replace \( x \) with 2 in the given function.
[tex]\[
f(2) = 3(2) - 12
\][/tex]
3. Simplify the expression:
[tex]\[
f(2) = 6 - 12
\][/tex]
4. Calculate the result:
[tex]\[
6 - 12 = -6
\][/tex]
So, \( f(2) = -6 \).
Thus, the correct answer is [tex]\( \boxed{-6} \)[/tex].
