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

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

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

Answer :

We are given the function
[tex]$$
f(x) = 7x - 4.
$$[/tex]

To find [tex]$f(6)$[/tex], substitute [tex]$x = 6$[/tex] into the function:

[tex]$$
f(6) = 7 \cdot 6 - 4.
$$[/tex]

First, compute the multiplication:

[tex]$$
7 \cdot 6 = 42.
$$[/tex]

Then, subtract 4 from 42:

[tex]$$
42 - 4 = 38.
$$[/tex]

Thus, the value of [tex]$f(6)$[/tex] is [tex]$\boxed{38}$[/tex], which corresponds to option C.
