You can put this solution on YOUR website!
$\"y=sqrt%28x%29\"$ and $\"y=-sqrt%28x%29\"$
\n" ); document.write( "Look the same only $\"y=-sqrt%28x%29\"$ is upside down.
\n" ); document.write( "Plot a few points:
\n" ); document.write( "In $\"y=sqrt%28x%29\"$
\n" ); document.write( " $\"y=sqrt%280%29=0\"$ Plot(0,0)
\n" ); document.write( " $\"y=sqrt%284%29=2\"$ Plot(4,2)
\n" ); document.write( " $\"y=sqrt%289%29=3\"$ Plot(9,3)
\n" ); document.write( "Connect the dots and you have a graph:
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Csqrt%28x%29%29\"$
\n" ); document.write( "In $\"y=-sqrt%28x%29\"$
\n" ); document.write( " $\"y=-sqrt%280%29=0\"$ Plot(0,0)
\n" ); document.write( " $\"y=-sqrt%284%29=-2\"$ Plot(4,-2)
\n" ); document.write( " $\"y=-sqrt%289%29=-3\"$ Plot(9,-3)
\n" ); document.write( "Connect the dots and you have a graph:
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-sqrt%28x%29%29\"$
\n" ); document.write( "Together you have:
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Csqrt%28x%29%2C-sqrt%28x%29%29\"$
\n" ); document.write( "That happens with all functions.
\n" ); document.write( " $\"y=-x%5E2\"$ looks like $\"y=x%5E2\"$ See:
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Cx%5E2%2C-x%5E2%29\"$
