limits

I'm studying the definitions of limits: lim F(x)=L x>a F(x)L<ÃÂ® 0<xa<ÃÂ« I'm having trouble solving proofs for constant values... for example: lim 2x^2=2 x>1 here' what I did: 2x^22<ÃÂ® 0<x1<ÃÂ« 2x^21<ÃÂ® 2x1x+1<ÃÂ® x+1<k 2(k)x1<ÃÂ® x1<ÃÂ®/2k 0<x1<ÃÂ« ÃÂ«=ÃÂ®/2k This is as far as I can get... The book solves for 'k' and comes up with this ÃÂ«=min(ÃÂ®/6,1) how do you find 'k'???
