To determine the value of [tex]\( f(x) \)[/tex] when [tex]\( x = 8 \)[/tex] for the function [tex]\( f(x) = 6x - 4 \)[/tex]:
1. Start by substituting [tex]\( x = 8 \)[/tex] into the function [tex]\( f(x) \)[/tex]:
[tex]\[
f(8) = 6 \cdot 8 - 4
\][/tex]
2. Next, perform the multiplication:
[tex]\[
6 \cdot 8 = 48
\][/tex]
3. Then, subtract 4 from the result:
[tex]\[
48 - 4 = 44
\][/tex]
Thus, the value of [tex]\( f(x) \)[/tex] when [tex]\( x = 8 \)[/tex] is [tex]\( 44 \)[/tex]. Therefore, the correct answer is [tex]\( 44 \)[/tex].
