Answer :
To find [tex]\( f(6) \)[/tex] for the function [tex]\( f(x) = 7x - 4 \)[/tex], we need to substitute [tex]\( x = 6 \)[/tex] into the function and then simplify.
Here's how you do it step-by-step:
1. Start with the given function:
[tex]\[
f(x) = 7x - 4
\][/tex]
2. Substitute [tex]\( x = 6 \)[/tex] into the function:
[tex]\[
f(6) = 7(6) - 4
\][/tex]
3. Calculate [tex]\( 7 \times 6 \)[/tex]:
[tex]\[
7 \times 6 = 42
\][/tex]
4. Subtract 4 from 42:
[tex]\[
42 - 4 = 38
\][/tex]
Therefore, the value of [tex]\( f(6) \)[/tex] is 38. So, the correct answer is A. 38.
