Answer:
B. f(x) = 8x + 2
Explanation:
You can start by checking the first answer
f(x) = 8x + 2
Use the first row of numbers
Use x as the numbers in the 'In' column
f(x) is the numbers in 'Out' column
Therefore:
8x + 2
8(-4) + 2 = - 30
-32 + 2 = 30
This statement is correct
Therefore the correct answer is A.
