Answer :
To find [tex]\( f(6) \)[/tex] for the function [tex]\( f(x) = 7x - 4 \)[/tex], you'll substitute 6 for [tex]\( x \)[/tex] in the function. Here's how you do it step-by-step:
1. Start with the function [tex]\( f(x) = 7x - 4 \)[/tex].
2. Substitute [tex]\( x = 6 \)[/tex] into the function:
[tex]\[
f(6) = 7 \times 6 - 4
\][/tex]
3. Begin by calculating [tex]\( 7 \times 6 \)[/tex]:
[tex]\[
7 \times 6 = 42
\][/tex]
4. Next, subtract 4 from 42:
[tex]\[
42 - 4 = 38
\][/tex]
So, the value of [tex]\( f(6) \)[/tex] is 38.
The correct answer is:
