Evaluate each function rule for x = - 1/2 f (x) = 4 (-1/2) - 2

f (-1/2) = - 4

Step-by-step explanation:

To evaluate the expression, substitute by replacing x with - 1/2. Then simplify according to order of operations:

f (-1/2) = 4 (-1/2) - 2

f (-1/2) = - 4/2 - 2

f (-1/2) = - 2 - 2

f (-1/2) = - 4
