$\"y%5E2=x%5E3-4x\"$ \r
\n" ); document.write( "\n" ); document.write( "set $\"x=0\"$ and solve for $\"y\"$ to find $\"y-intercept\"$ :\r
\n" ); document.write( "\n" ); document.write( " $\"y%5E2=0%5E3-4%2A0=0\"$ ......... $\"y=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y-intercept\"$ is at origin ( $\"0\"$ , $\"0\"$ )\r
\n" ); document.write( "\n" ); document.write( "set $\"y=0\"$ and solve for $\"y\"$ to find $\"y-intercept\"$ :\r
\n" ); document.write( "\n" ); document.write( " $\"0=x%5E3-4x\"$ ...=>.. $\"0=x%28x%5E2-4%29\"$ ..=>. $\"0=x%28x-2%29%28x%2B2%29\"$ .....so, $\"0=x\"$ or $\"x=2\"$ or $\"x=-2\"$ \r
