You can put this solution on YOUR website!
state the domains for:
\n" ); document.write( "g(x)= 2x + 1/x - 3
\n" ); document.write( "The domain on this one is all real number except +3, you can see that if x = 3
\n" ); document.write( "we would have division by 0, a big no-no
\n" ); document.write( ":
\n" ); document.write( "h(x) = 3x^2 + 5x - 3
\n" ); document.write( "A parabola, all real numbers
\n" ); document.write( ":
\n" ); document.write( "l(x) = 2x + 3
\n" ); document.write( "A linear line, all real numbers
\n" ); document.write( ":
\n" ); document.write( "m(x) = 3/x^2+7
\n" ); document.write( "Even tho this one has a denominator, there is no way that x^2 can be -7 so it
\n" ); document.write( "is all real numbers also
\n" ); document.write( "
\n" ); document.write( "
\n" );
