You can put this solution on YOUR website!
f(x)=

\n" ); document.write( "{2x+2, x>=1
\n" ); document.write( "find the following limits
\n" ); document.write( "lim f(x) =
\n" ); document.write( "x->1+
\n" ); document.write( "--
\n" ); document.write( "Comment: The x is approaching 1 from the right side (above) so
\n" ); document.write( "you use 2x+2 to evaluate the \"limit as x approaches 1+ and
\n" ); document.write( "you get 2*1+2 = 4
\n" ); document.write( "------------------------------------------------

\n" ); document.write( "---------------------------------------------------
\n" ); document.write( "lim f(x) =
\n" ); document.write( "x->1
\n" ); document.write( "Comment: Since the limit from the left does not equal
\n" ); document.write( "the limit from above \"the limit as x approaches 1\" does
