To find [tex]\( f(6) \)[/tex] for the function [tex]\( f(x) = 7x - 4 \)[/tex], follow these steps:

1. Substitute [tex]\( x = 6 \)[/tex] into the function:
[tex]\[
f(6) = 7(6) - 4
\][/tex]

2. Multiply 7 by 6:
[tex]\[
7 \times 6 = 42
\][/tex]

3. Subtract 4 from the result:
[tex]\[
42 - 4 = 38
\][/tex]

Therefore, the value of [tex]\( f(6) \)[/tex] is 38. The correct answer is B. 38.
