You can put this solution on YOUR website!
Y = SQRT(9-4X)
\n" ); document.write( "THE FUNCTION IS NOT DEFINED IF 9-4X UNDER RADICAL SIGN IS NEGATIVE.
\n" ); document.write( "HENCE 9-4X>=0
\n" ); document.write( "9>=4X
\n" ); document.write( "9/4=2.25>=X
\n" ); document.write( "X<=2.25
\n" ); document.write( "SO DOMAIN OF THE FUNCTION IS ALL REAL VALUES >=2.25...THAT IS
\n" ); document.write( "(-INFINITY,2.25]
\n" ); document.write( "
\n" );
