Determine the domain of the rational function:
\n" ); document.write( "R(x)= (x-5)/(4x-9)(x+1)
\n" ); document.write( "**
\n" ); document.write( "R(x)= (x-5)/(4x-9)(x+1)
\n" ); document.write( "Set denominator=0, then solve for x.
\n" ); document.write( "(4x-9)(x+1)=0
\n" ); document.write( "4x-9=0
\n" ); document.write( "x=9/4
\n" ); document.write( "and
\n" ); document.write( "x+1=0
\n" ); document.write( "x=-1
\n" ); document.write( "{x|x≠-1, x≠9/4}
\n" ); document.write( "Domain: (-∞, -1) U (-1, 9/4) U (9/4, ∞) \n" ); document.write( "

\n" );
