Sagot :

To determine the value of the function [tex]\( f(x) = 6x - 4 \)[/tex] when [tex]\( x = 8 \)[/tex], follow these steps:

1. Start with the given function [tex]\( f(x) = 6x - 4 \)[/tex].

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

3. First, perform the multiplication within the function:
[tex]\[ 6 \times 8 = 48 \][/tex]

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

So, the value of [tex]\( f(x) \)[/tex] when [tex]\( x = 8 \)[/tex] is [tex]\( 44 \)[/tex].
