Answer :
To find [tex]\( f(6) \)[/tex] for the function [tex]\( f(x) = 7x - 4 \)[/tex], you can follow these steps:
1. Substitute 6 for [tex]\( x \)[/tex] in the function.
- The function is defined as [tex]\( f(x) = 7x - 4 \)[/tex]. So, substitute 6 into the function:
[tex]\[
f(6) = 7(6) - 4
\][/tex]
2. Perform the multiplication.
- Calculate [tex]\( 7 \times 6 \)[/tex]:
[tex]\[
7 \times 6 = 42
\][/tex]
3. Subtract 4 from the result.
- Now subtract 4 from 42:
[tex]\[
42 - 4 = 38
\][/tex]
So, the value of [tex]\( f(6) \)[/tex] is 38. Therefore, the correct answer is D. 38.
