Evaluate the function at that point: 1stanswer = (choice)2 +
(choice).
Now iterate, that is, put this answer back into the function: 2nd answer
= (1stanswer)2 + (choice).
Do this until the (nth answer) is the same as the ((n - 1)th answer).
This means that the point stays in that position for every iterate after. Some points
hop between points. If it is within a particular radius of the origin, then it is in the set.
