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. First, substitute [tex]\( x = 6 \)[/tex] into the function.

So, we have:
[tex]\[
f(6) = 7 \cdot 6 - 4
\][/tex]

2. Next, perform the multiplication:

[tex]\( 7 \cdot 6 = 42 \)[/tex].

3. Then, subtract 4 from 42:

[tex]\( 42 - 4 = 38 \)[/tex].

Therefore, [tex]\( f(6) = 38 \)[/tex].

The correct answer is B. 38.
