Give the values of x which must be excluded from the domain of the following function.
\n" ); document.write( "f(x)= (x+1)/(x^2-4x-12)
\n" ); document.write( "Factor to get:
\n" ); document.write( "f(x)/[(x-6)(x+2)]
\n" ); document.write( "------------------
\n" ); document.write( "X-values are excluded if they make the denominator zero or if they
\n" ); document.write( "make a radicand negative for radicals with even index.
\n" ); document.write( "--------------
\n" ); document.write( "Your Problem:
\n" ); document.write( "You have no radicals, so forget that.
\n" ); document.write( "You have a denominator so x cannot be 6 and it cannot be -2.
\n" ); document.write( "------------
\n" ); document.write( "Therefore the domain is All Real Numbers except x=-2 and x=6.
