Using the definition of the derivative, find f'(x). Then find f'(-3), f'(0), and f'(1) when the derivative exists. f(x) = 2x +2 f'(x) = Find f'(-3) if the derivative exists. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. f'(-3)= (Simplify your answer.) OB. The derivative does not exist. Find f'(0) if the derivative exists. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. f'(0) = (Simplify your answer.) OB. The derivative does not exist. Find f'(1) if the derivative exists. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. f'(1)= (Simplify your answer.) OB. The derivative does not exist.
