This is a problem related to julia sets but its more of a mathematical problem so I posted it here.(adsbygoogle = window.adsbygoogle || []).push({});

x= x^2 - 2

For what values the iteration does not go to infinity. I can't figure out how to calculate that. I tried calculating a nth term of this in terns of initial term but all in vain.
