------------------------------------------------ Let [tex]$f(x)=7x-4$[/tex].

What is [tex]$f(6)$[/tex]?

A. 46
B. 38
C. 42
D. 48

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
```
