You can put this solution on YOUR website!
The x-intercept occurs where $\"+y+=+0+\"$
\n" ); document.write( "The y-intercept occurs where $\"+x+=+0+\"$
\n" ); document.write( "--------------------------------
\n" ); document.write( "There can be more than one x-intercept,
\n" ); document.write( "but there can be only one y-intercept
\n" ); document.write( "-------------------------------
\n" ); document.write( "Suppose you have the equation $\"+y+=+x%5E2+-+4+\"$
\n" ); document.write( "To find the x-intercept(s),
\n" ); document.write( " $\"+0+=+x%5E2+-+4+\"$
\n" ); document.write( " $\"+x%5E2+=+4+\"$
\n" ); document.write( " $\"+x+=+2+\"$
\n" ); document.write( " $\"+x+=+-2+\"$
\n" ); document.write( "----------
\n" ); document.write( "And, to find the y-intercept,
\n" ); document.write( " $\"+y+=+0%5E2+-+4+\"$
\n" ); document.write( " $\"+y+=+-4+\"$
\n" ); document.write( "----------
\n" ); document.write( "Here's the plot:
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-5%2C+5%2C+-5%2C+5%2C+x%5E2+-+4+%29+\"$ \n" ); document.write( "
