if f(x) = 6x - 4, what is f(x) when x = 8?\n2\n16\n44\n52

Explanation:

Step1: Substitute x value

Substitute $x = 8$ into $f(x)=6x - 4$. $f(8)=6\times8 - 4$

Step2: Perform multiplication

Calculate $6\times8$. $6\times8=48$, so $f(8)=48 - 4$

Step3: Perform subtraction

$48-4 = 44$

Answer:

C. 44
