8. (10 points) Sections 2.1-2.3 a. Let f(2) = (29 - 3iz + mi)-2081 , calculate f'(2) at all points where it is continuous (no need to find the domain) and then calculate lim f'(2). 200 (22 + 1)2 b. Let f (2) = (22 + iz + 1)3: calculate lim f(2) and then calculate f'(2 ) at all points where it 2 is differentiable
