To determine the value of the function [tex]\( f(x) = 6x - 4 \)[/tex] when [tex]\( x = 8 \)[/tex], follow these steps:
1. Substitute [tex]\( x = 8 \)[/tex] into the function [tex]\( f(x) \)[/tex]:
[tex]\[
f(8) = 6(8) - 4
\][/tex]
2. Multiply 6 by 8:
[tex]\[
6 \cdot 8 = 48
\][/tex]
3. Subtract 4 from 48:
[tex]\[
48 - 4 = 44
\][/tex]
Therefore, [tex]\( f(8) = 44 \)[/tex].
The value of [tex]\( f(x) \)[/tex] when [tex]\( x = 8 \)[/tex] is [tex]\( 44 \)[/tex], so the correct answer is:
44
