find the first three outputs of each fractal-generating function?

Question

f(z)=i-z squared
i think the answers are i,1+i,i am i right

Answer 1

f(0) = i - 0² = i

f(i) = i - i² = i - (-1) = 1 + i

f(1 + i) = i - (1 + i)² = i - (1 + 2i + i²) = i - (1 + 2i - 1) = i - 2i = -i

I think maybe the third one should be -i. The rest I think are correct.
