Answer :
Sure! Let's find the value of [tex]\( f(6) \)[/tex] for the function [tex]\( f(x) = 7x - 4 \)[/tex].
1. Start with the function:
[tex]\[
f(x) = 7x - 4
\][/tex]
2. Substitute [tex]\( x = 6 \)[/tex] into the function:
[tex]\[
f(6) = 7(6) - 4
\][/tex]
3. Perform the multiplication:
[tex]\[
f(6) = 42 - 4
\][/tex]
4. Subtract 4 from 42:
[tex]\[
f(6) = 38
\][/tex]
So, the value of [tex]\( f(6) \)[/tex] is 38. Therefore, the correct answer is:
```
B. 38
