A.2
B.16
C.44
D.52

Answer 1

Explanation:

`f(x) = 6x -4 \\ f(8) \\ f(x) = 6(8) - -4 \\ f(x) = 48 - 4 \\ f(x) = 44</p><p>`

Answer 2

C.44

Explanation:

Basically, the question is asking for you to plug in 8 for x into the equation, since the function of x is represented by the equation. Therefore, plug in 8 into the equation like this: 6(8)-4

Multiply 6 and 8, then subtract 4 from the product to get your answer
