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

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

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

Answer :

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

1. Start with the given 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]\[ 7 \times 6 = 42 \][/tex]

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

So, [tex]\( f(6) \)[/tex] is [tex]\( 38 \)[/tex].

The correct answer is:
B. 38
