Answer :

To solve the problem, we need to evaluate the function [tex]\( f(x) = 6x - 4 \)[/tex] at [tex]\( x = 8 \)[/tex].

Step-by-Step Solution:

1. Start by writing down the function provided:
[tex]\[ f(x) = 6x - 4 \][/tex]

2. Substitute [tex]\( x = 8 \)[/tex] into the function:
[tex]\[ f(8) = 6(8) - 4 \][/tex]

3. Perform the multiplication first:
[tex]\[ 6 \cdot 8 = 48 \][/tex]

4. Now, subtract 4 from the result of the multiplication:
[tex]\[ 48 - 4 = 44 \][/tex]

Therefore, [tex]\( f(8) = 44 \)[/tex].

So, the value of [tex]\( f(x) \)[/tex] when [tex]\( x = 8 \)[/tex] is [tex]\( 44 \)[/tex], and the correct answer is:
[tex]\[ 44 \][/tex]
