1/\"+sqrt%28x%5E2%2B3x-28+%29+\"=y what is the domain of the relation?
\n" ); document.write( "x^2+3x-28>0
\n" ); document.write( "(x+7)(x-4)>0
\n" ); document.write( "number line:
\n" ); document.write( "<..+...-7.....-....4...+....>
\n" ); document.write( "Domain: (-∞,-7) U (4,∞)\r
\n" ); document.write( "\n" ); document.write( "note: domain for radicans: ≥0
\n" ); document.write( "but since it is also in the denominator ≠0, must be>0.
\n" ); document.write( "
\n" );
