You can put this solution on YOUR website!
f(x)= (-3) / (x + 3)
\n" ); document.write( "--------------------------------------------------------------
\n" ); document.write( "This will be a sideways hyperbola....
\n" ); document.write( "Here are some points:
\n" ); document.write( "(0,-1);(-1,-3/2);(-2,-3);(-3,undefined);(-4,3);(-5,3/2);(-6,1)
\n" ); document.write( "------------------------------------------------------------------------------
\n" ); document.write( "the \"angle shaped\" line will not cross the y=0 constant line;
\n" ); document.write( "also, the vertical asymptote is x=-3 -- because in the equation, if you plug in -3, you get -3/0 and that is undefined
\n" ); document.write( "
\n" );
