To find [tex]\( f(2) \)[/tex] for the function [tex]\( f(x) = 3x - 12 \)[/tex], you need to substitute [tex]\( x = 2 \)[/tex] into the function. Here’s the step-by-step process:

1. Start with the given function:
[tex]\[ f(x) = 3x - 12 \][/tex]

2. Substitute [tex]\( x = 2 \)[/tex] into the function:
[tex]\[ f(2) = 3(2) - 12 \][/tex]

3. Perform the multiplication in the equation:
[tex]\[ 3 \cdot 2 = 6 \][/tex]
So the equation now looks like:
[tex]\[ f(2) = 6 - 12 \][/tex]

4. Finally, subtract 12 from 6:
[tex]\[ 6 - 12 = -6 \][/tex]

Therefore, the value of [tex]\( f(2) \)[/tex] is [tex]\(-6\)[/tex].

The correct answer is:
A. -6
