Hello,

to a):

Assume that f''(x) = 3 then

. With f'(0) = -4 you'll get C = -4

Thus f'(x) = 3x-4

Then . With f(0) = 2 you'll get C = 2 and therefore the function is:

to b)

I assume that you have to use the function f from a). Thus

Plug in x = 0 (Remember ) and the values for f'(0) and f''(0).
