$\"graph%28300%2C300%2C-10%2C10%2C-40%2C40%2Cx%5E2-8%2Cx%5E2%2B4x-21%29\"$
\n" ); document.write( ":
\n" ); document.write( " $\"x%5E2-8\"$ is red
\n" ); document.write( ":
\n" ); document.write( " $\"x%5E2%2B4x-21\"$ is green
\n" ); document.write( ":
\n" ); document.write( "we know that the green line should be dotted because the inequality doesnt have an equals with it so it is not inclusive\r
\n" ); document.write( "\n" ); document.write( "Plot some points on either side of each equation to see which side gets colored in for each inequality
\n" ); document.write( ":
\n" ); document.write( "for example try (0,0) for each\r
\n" ); document.write( "\n" ); document.write( "it works on the red graph but not for the green...
\n" ); document.write( ":
\n" ); document.write( "so it appears everything inside the red graph will work and everything outside the green parabola will be true \n" ); document.write( "

\n" );
