Answer :

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
