Complex Number Iteration ??

[rancid bay]

I don’t understand how what I need to do, I know what it means by second iterate though.

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

3. Feel free to nominate the person for helper of the week in #helper-nominations

The second iterate of f(z) is f(f(z)). So:
f(f(z)) = (z^2 - 1)^2 - 1 = z^2 (z^2 - 2)
So, just substitute z = 3 - i there.
