Answer :
To solve the problem, we need to evaluate the function [tex]\( f(x) = 7x - 4 \)[/tex] at [tex]\( x = 6 \)[/tex].
Here's how you can do it step-by-step:
1. Identify the function: The function is given as [tex]\( f(x) = 7x - 4 \)[/tex].
2. Substitute the given value: Replace [tex]\( x \)[/tex] with 6 in the function. So, it becomes [tex]\( f(6) = 7(6) - 4 \)[/tex].
3. Perform the multiplication: Calculate [tex]\( 7 \times 6 \)[/tex], which is 42.
4. Perform the subtraction: Subtract 4 from 42 to get [tex]\( 42 - 4 = 38 \)[/tex].
Therefore, the value of [tex]\( f(6) \)[/tex] is 38.
The correct answer is C. 38.
