You can put this solution on YOUR website!
The second part of your description is a circle, $\"%28x%2B3%29%5E2%2B%28y%2B1%29%5E2=25\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve for y as a function of x.
\n" ); document.write( " $\"%28y%2B1%29%5E2=25-%28x%2B3%29%5E2\"$
\n" ); document.write( " $\"y%2B1=0%2B-+sqrt%2825-%28x%2B3%29%5E2%29\"$
\n" ); document.write( " $\"highlight%28y=-1%2B-+sqrt%2825-%28x%2B3%29%5E2%29%29\"$ , which obviously is two different formulas for y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next, use x=1 for both branches of y, so you WILL find two values for y.
\n" ); document.write( "Obtain $\"y=-1%2B3\"$ and $\"y=-1-3\"$ ;
\n" ); document.write( " $\"highlight%28y=2%29\"$ or $\"highlight%28y=-4%29\"$ \n" ); document.write( "

\n" );
