Sure! Let's solve this step-by-step.
We are given the function [tex]\( f(x) = 6x - 4 \)[/tex] and we need to find the value of the function when [tex]\( x = 8 \)[/tex].
1. Substitute [tex]\( x = 8 \)[/tex] into the function:
[tex]\[
f(8) = 6(8) - 4
\][/tex]
2. Calculate the multiplication within the function:
[tex]\[
f(8) = 48 - 4
\][/tex]
3. Subtract 4 from 48:
[tex]\[
f(8) = 44
\][/tex]
Therefore, when [tex]\( x = 8 \)[/tex], [tex]\( f(x) \)[/tex] equals 44. Thus, the correct answer is [tex]\( \boxed{44} \)[/tex].
