What is the domain of
\n" ); document.write( "(((t^3)+8)/((t^2)+6t+8))
\n" ); document.write( "When the denominator=0, the expression becomes undefined.
\n" ); document.write( "So, set the denominator=0 and solve for x.
\n" ); document.write( "(t^2)+6t+8=0
\n" ); document.write( "(t+4)(t+2)=0
\n" ); document.write( "t=-4
\n" ); document.write( "or
\n" ); document.write( "t=-2
\n" ); document.write( "Domain: all real numbers except x=-4 and -2
\n" ); document.write( "(-∞,-4) U (-4,-2) U (-2,∞) \n" ); document.write( "

\n" );
