To solve for [tex]\( f(x) \)[/tex] when [tex]\( x = 8 \)[/tex], we need to substitute [tex]\( x = 8 \)[/tex] into the given function [tex]\( f(x) = 6x - 4 \)[/tex].

Here's the step-by-step solution:

1. Start with the given function:
[tex]\[ f(x) = 6x - 4 \][/tex]

2. Substitute [tex]\( x = 8 \)[/tex] into the function:
[tex]\[ f(8) = 6(8) - 4 \][/tex]

3. First, perform the multiplication:
[tex]\[ 6 \times 8 = 48 \][/tex]

4. Then, subtract 4 from the result:
[tex]\[ 48 - 4 = 44 \][/tex]

Therefore, [tex]\( f(8) = 44 \)[/tex].

So, when [tex]\( x = 8 \)[/tex], [tex]\( f(x) = 44 \)[/tex].

Among the given choices, the correct answer is:
[tex]\[ \boxed{44} \][/tex]
