OPTIONS ARE: f(x)= 6 , f(x)= -5 , f(x)= -12 , f(x)= 1

f(x) = 6 when x = -3

Step-by-step explanation:

Looking at the problem, it gives you two scenarios to get f(x):

1) When x is less than 0, multiply x by -2.

2) When x is greater than or equal to 0, multiply x by 4.

As defined by the question, x = -3. Since -3 is less than 0, you would go to scenario 1, which multiplies x (-3) by -2, giving you 6.

x + 4/7
