You can put this solution on YOUR website!
we presume the problem is ,,,1/x<=x^2-1
\n" ); document.write( ".
\n" ); document.write( "by inspection ,,,,
\n" ); document.write( ".
\n" ); document.write( "if x=0,,,1/x is undefined
\n" ); document.write( ".
\n" ); document.write( "if x=1,,,,,1<=1-1,,,1<=0,,,not true
\n" ); document.write( ".
\n" ); document.write( "if x=2,,,,1/2<=2^2-1,,,,,1/2<=3,,,ok
\n" ); document.write( ".
\n" ); document.write( "appears to be x>1
\n" ); document.write( ".
\n" ); document.write( "to math calc
\n" ); document.write( ".
\n" ); document.write( "1/x <=(x^2-1)
\n" ); document.write( ".
\n" ); document.write( "mult by x
\n" ); document.write( ".
\n" ); document.write( "1<=x^3 -x
\n" ); document.write( ".
\n" ); document.write( "take log's
\n" ); document.write( ".
\n" ); document.write( "log1<=logx^3-logx
\n" ); document.write( ".
\n" ); document.write( "0<=3logx-1logx
\n" ); document.write( ".
\n" ); document.write( "0<=2logx
\n" ); document.write( ".
\n" ); document.write( "0<=logx
\n" ); document.write( ".
\n" ); document.write( "x>=1,,,,,checking x=1,,not true ,,,therefore x>1
